Question

A circle has its center at the center of a square with 3-inch sides. Find the area of the square not covered by the circle. Round the answer to the nearest tenth.

Answer 1

the diameter of the circle is 3in. Why? the diameter is parallel to a side. So we will calculate the area of the circle and subtract that value from the area of the square.

so area of the square=l*w=3*3=9
area of the circle=\[\pi \times r^{2}\]=\[\pi\times 3/2^{2}\]. THIS YIELDS:
\[9- 9/4 \times \pi\]

then put into a calculator and get
A=\[6.75 \pi\]
