Question

4. If the area of a semi-circle is 100.48 square inches, what is the radius

of the circle ? *
A) 16 inches
B) 8 inches
C) 4 inches
D) 2 inches

Answer 1

If we take the area which is 100.48, and multiply it by 2 because it’s obviously a semi-circle and we’re looking for the radius, we will get 200.96. Then we divide it by 3.14 to get 64. Then square root 64 to get 8. So it’s B.
