You can put this solution on YOUR website! I need to find the surface area of a 11 by 8 piece of paper when rolled into a cylinder.

11*8 = 88 sq units (each side) regardless of what shape it's formed into.
Answer by Cromlix(3061) (Show Source):
You can put this solution on YOUR website! Hi there,
If you think of a cylinder being
cut down one side and opened, it would become
a rectangle.
The circumference of the cylinder
would become either the 11 or the 8.
The height of the cylinder would be either
the 11 or the 8.
So the surface area of the outside would
equal 11 x 8 = 96 square units.
Hope this helps :)

Question 994095: The measure of the largest angle of a triangle is 10 degrees more than the sum of the measures of the other two angles and 10 degrees less than 3 times the measure of the smallest angle. Find the measures of the three angles of the triangle.
Answer by ankor@dixienet.com(18980) (Show Source):
You can put this solution on YOUR website! The measure of the largest angle of a triangle is 10 degrees more than the sum of the measures of the other two angles and 10 degrees less than 3 times the measure of the smallest angle.
Find the measures of the three angles of the triangle.
:
let the 3 angles be A, B, C, with A being the largest
:
"The measure of the largest angle of a triangle is 10 degrees more than the sum of the measures of the other two angles"
A = B + C + 10
" and 10 degrees less than 3 times the measure of the smallest angle.
A = 3C  10
We also know that
A + B + C = 180
Rewrite the 1st equation and add to the above equation
A + B + C = 180
A  B  C = 10
Adding eliminates B and C, find A
2A + 0 + 0 = 190
A = 190/2
A = 95 degrees
Find C using the 2nd equation
A = 3C  10
95 = 3C  10
95 + 10 = 3C
105 = 3C
C = 105/3
C = 35 degrees
Find B
95 + B + 35 = 180
B + 130 = 180
B = 180  130
B = 50 degrees
:
the measures of the three angles: 95, 50, 35
Question 993983: Bob and Carol want to hire Able Refinishing to sand and refinish the dining room floor to match the floor in the living room. Able charges $2.89 per square foot to sand and refinish a hardwood floor. The dining room is rectangular and measures 17 feet 8 inches by 11 feet 8 inches. Find the area of the dining room floor, rounded up to the next square foot, and the cost of the work
Answer by addingup(248) (Show Source):
You can put this solution on YOUR website! OK, so 17 feet is 17x12= 204+8= 212 inches is the length
And 11 feet is 11x12= 132+8= 140 inches is the width.

The area of a rectangle is LxW= 212x140= 29,680 square inches.
Now, we are talking about SQUARED numbers, right? So, 1 foot = 12 inches and 1 square foot = 12^2=144 inches.

We said the room is 29,680 square inches, and 29,680/144= 206.11 and we round off to the nearest foot = 206 square feet.
And the cost?: 206x2.89= $595.34

Question 993674: the length of a rectangle is 1 inch less than twice that of its width. If the perimeter measures 49 inches, then find the dimensions of the rectangle.
Answer by fractalier(2141) (Show Source):
You can put this solution on YOUR website! L = 2W  1
P = 2L + 2W = 49
Now substituting, we get
2(2W  1) + 2W = 49
4W  2 + 2W = 49
Simplifying we get
6W = 51 and
W = 8.5
Then
L = 2W  1 = 2(8.5)  1 = 17  1 = 16
Question 993629: A rectangular parcel of land is 20 m wide. The length of the diagonal between the opposite corners is 5 m more than the length of the parcel. What is the length of the parcel?
Found 2 solutions by Cromlix, stanbon: Answer by Cromlix(3061) (Show Source):
You can put this solution on YOUR website! Hi there,
Imagine you have a right angled triangle.
Width = 20 meters
Length = x
Diagonal = x + 5
(20)^2 + (x)^2 = (x + 5)^2
400 + x^2 = x^2 + 10x + 25
Collect like terms.
10x = 400  25
10x = 375
x = 37.5 meters
Length of parcel = 37.5 meters.
Hope this helps :)
Answer by stanbon(69061) (Show Source):
You can put this solution on YOUR website! A rectangular parcel of land is 20 m wide. The length of the diagonal between the opposite corners is 5 m more than the length of the parcel. What is the length of the parcel?

Draw the picture of the rectangle.
width = 20 m
length = x meters
diagonal = x+5 meters

Solve for "x"::
(x+5)^2 = x^2 + 400

x^2+10x + 25 = x^2 + 400
10x = 375
x = 37.5 meters (length)

Question 993337: Give the dimension of the water tank, use its diagonal for the height.l = 125 cm and width = 129 cm. How to determine the diagonal of the rectangular water tank?
Answer by Theo(5548) (Show Source):
You can put this solution on YOUR website! the length is 125 cm.
the width is 129 cm.
the diagonal and the length and the width form a right triangle with one leg = 125 cm and the other leg = 139 cm.
the diagonal is equal to sqrt(125^2 + 129^2) = 179.6273921 cm
you are using the pythagorian formula of a right triangle which is:
H^2 = L1^2 + L2^2
H is the hypotenuse
L1 is one of the legs of the right triangle.
L2 is the other leg of the right triangle.
take the square root of H^2 and you have H.

Question 993175: two cylindrical ice pillars will flank the front door. Each cylinder has a diameter of 1 foot and height of 9 feet. The ice weighs 62.4 pounds per cubic feet.
Answer by Cromlix(3061) (Show Source):
You can put this solution on YOUR website! Hi there,
I assume that you are looking for the total weight
of these cylinders.
Formula:Volume = Pi x r^2 x h
Volume = Pi x 0.5^2 x 9
Volume = 7.069 ft^3
At 62.4 pounds per cubic foot
The weight of one cylinder =
62.4 x 7.069
= 441.11 pounds per cylinder
or 882.22 pounds for two cylinders.
Hope this helps :)

The Leaning Tower is 804 ft. shorter than the Eiffel Tower in Paris, France. The two towers have a total height of 1,164 ft. How tall is each tower?

LT = ET804
LT + ET = 1164

ET804 + ET = 1164
2*ET = 1908
ET = 954 ft (height of Eiffel Tower)
LT = 954804 = 150 (height of Leaning Tower)
============
Cheers,
Stan H.

Answer by Cromlix(3061) (Show Source):
You can put this solution on YOUR website! Hi there,
Assume that the Eiffel Tower = 'x'
Leaning Tower = x  804.
Therefore:
x + (x  804) = 1,164 ft
x + x  804 = 1,164 ft
2x  804 = 1,164
2x = 1,164 + 804
2x = 1,968
x = 984 ft
Eiffel Tower = 984 ft
The Leaning Tower = 180 ft

But, what are the dimensions in feet? How do I convert? Thanks.
Found 2 solutions by vleith, rothauserc: Answer by vleith(2950) (Show Source): Answer by rothauserc(2272) (Show Source):
You can put this solution on YOUR website! The border will be inside the dimensions of the room, therefore
(192x) * (182x) = 272
342  74x + 4x^2 = 272
rearrange the terms
4x^2  74x + 342 = 272
divide both sides of = by 4
x^2  18.5x + 85.5 = 68
subtract 68 from both sides of =
x^2  18.5x + 17.5 = 0
use quadratic formula to solve for x
x = ((18.5) + sqrt((18.5^2)−(4×17.5))) / 2 = 17.5
x = ((18.5)  sqrt((18.5^2)−(4×17.5))) / 2 = 1
****************************************************************
The reasonable dimension for the strip around the rug is 1 foot, therefore
the dimensions for the rug are 17 feet long and 16 feet wide

Question 992131: The length and breadth of a page of my exercise book is 15 cm and 12 cm. A margin of width 2 cm is drawn on all sides and wrote inside the margin. Find the area of portion on which I wrote and also find the area of the portion on which I have not written
Answer by solver91311(20879) (Show Source):
You can put this solution on YOUR website!
The overall area of the page is the product of the length and width of the page. The area of the page containing writing is the length of the page minus 2 times the width of the margin times the width of the page minus 2 times the width of the margin. The area of the margin is the total area of the page minus the area of the page containing writing.
