Question

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approximate pi.

Answer 1

The correct answer is 168.56

Explanation:

I did the k12 quiz and got a hundred.

Answer 2

the answer is around 168.56

work :

the side of the square is 28 in


so the diameter of the circle is 28 in, too(look at the picture)

then the radius is 14 (28/2)


the area of the circle is

`(14 * 14) * 3.14 = 615.44`

the area of the square is

`{28}^(2) = 784`


so the area of the shaded region will be around:

`784 - 615.44 = 168.56`


good luck
