Question:

A
3.2 cm

Explaination

The formula for the circumference of a circle is $2990_w66_h12.png$. Plug in the given circumference and solve for the radius.

$5773_w66_h12.png$

$6393_w70_h12.png$

$8481_w60_h13.png$

Use 3.14 as an approximate value for π and divide to solve. Round to the nearest tenth. r = 3.2
