➷ 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
