Question

A circle is cut from a square piece of cloth, as shown:

A square, one side labeled as 38 inches, has a circle inside it. The circle touches all the sides of the square. The portion of the square outside the circle is shaded.

How many square inches of cloth are cut from the square? (π = 3.14)

Answer 1

the square has a side of 38, so dividing that by 2 will give you the radius of the circle inside of it. The radius would be 19, and using it in the circle area formula(πr^2) will give you the answer:
A=pi(19)^2
A=361pi
A= 1133.54inches^2
