Question 131013: A cow is tethered to one corner of a square barn, 10 feet by 10 feet, with a rope 100ft long. What is the maximum grazing area for the cow. I know that the answer is 31,145.15 ft squared. I figured out that the left side of the circle has an area of 49348feet. the other semicircular shape - it is not a true semicircle- is split up into three four areas. a quarter circle on the bottom right, sector on the upper right a sector on the right side and a triangle between those two sectors.
please show all your work.
thank you!

Question 132152: Find the area of the circle.
Theres a square with a circle inside of it, but the cirlce is small enought to where you are still able to see the square. Only the corners of each side kind of like a triangel but where its not straight on the bottom, but rounded. You have to fing the area if the perimeter of square = 144 ft
What do you do? how do you find the area if you only have the perimeter and nothing else?
thank you, very much!

Question 134188: Find the area and perimeter of the shaded region.
note: The radius of the circle is 4.
What I've done:
I know you have to find the area of the small unshaded seg. by doing A seg. = Asec.-A triangle. Then you need to find the area of the semi-circle created by the shaded area and the segment. Then if you subtract the area of the segment from the area of the semi-circle you get the area of the shaded region. I just don't get how to find the area of the semi circle and I don't know what to input into the formula for finding the area of the SEGMENT.
I also have no clue how to find the perimeter of the shaded area!
PLEASE HELP!

Question 135162: A team in science class placed a chalk mark on the side of the wheel and rolled the wheel in a straight line until the chalk mark returned to the same position. The team then measured the distance the wheel had rolled and found it to be 56 cm. To the nearest tenth, what is the radius of the wheel?
I don't get how I'm supposed to solve this..?
