### A circle has its center at the center of a square with 12-inch sides.

Using 3.14 for pi, find the area of the square not covered by the circle, then write a ratio of the circle?
s circumference to the perimeter of the square.

So first, find the area of the square.
12x12= 144inches^2 Then find the area of the circle.
To do this we use pi x r^2.
The radius of the circle is 6 inches.
Pi x 6^2 = 113.04inches^2.
144 - 113.04 = 30.6, so your answer is 30.6 inches^2 The circles circumference is worked out by using pi x d.
The diameter is 12 inches, so 3.14x12 = 37.68 inches.
The squares perimeter is 12 x 4 = 48 inches.
If you round up the circumference of the circle to the nearest integer, you get 38 inches.
The ratio would therefore be, 38:48, which can be rounded down to 19:24 :)
