➷ The formula for circumference is \pi d

1) \pi d = 31.4

Divide both sides by \pi

d = 9.99 (consider this to be 10)

Half this to find the radius

10/2 = 5

It would be figure B.

2) \pi d = 37.68

Divide both sides by \pi:

d = 11.99 (consider this to be 12)

Divide by 2 to find the radius:

12/2 = 6

It would be figure C.

3) area = \pi r^2

\pi r^2 = 153.86

r^2 = 48.97515909

r = 6.998 (consider this to be 7)

It would be figure D

4) \pi r^2 = 113.04

r^2 = 35.98174

r = 5.998 (consider this to be 6)

It would be figure C.

5) radius = diameter / 2

radius = 3

\pi (3)^2 = 28.27433

It would be option C

➶ Good Luck (:
