Question 142296: Hello, I am wondering if anyone can tell me if I am in the right direction for answering the following problem.
On a sunny day a flag pole and its shadow form the sides of a right triangle. If the hypotenuse is 35m long and the shadow is 28m how tall is the flag pole.
I have A^2 + 28^2 = square root of 35^2
A^2 + 784 = 35
A^2 = 35-784
A^2 = -749
A^2 = 27.37 meter is what the folow pole is.
I am doing a unit on different types of square and nth root applications and ths is my first time learning such items ( I am in my 40's!!) so any help is appreciated. Thank you.

Question 144280: A cylindrical water tank with radius 2 feet and length 6 feet is filled with water to a depth of 3 feet when in a horizontal position. If the tank is turned upright, what is the depth of the water? Give answer in terms of pi.
Find the volume of water. The volume is the area x length.
The area of the segment is:
The values listed (using an Excel sheet I made) give a cross-sectional area of:
10.10963 sq ft
6 times that is: 60.657787 cubic ft
The volume of a "vertical" cylinder is  , in this case PIx4xh, so
h = Vol/4PI, which is 4.82699 feet. In terms of PI, it's 15.16445/PI

Question 144637: The floor of a rectangular room that measures 10 feet by 12 feet is partially covered by a circular rug with a radius of 4 feet. What percent of the floor is covered by the rug? (Hint: The area of a circle is A=(oie sign)r2).
So I know that radius of the rug which I believe is 16 (pie sign) which means that 44 is the entire area - 16 which leaves you with 28, I'm just having a problem with how to set this problem up and come up with the answer which I believe is right around 63.6363% but I still need to know how to set up the problem.
