Answer 1

To find out the circumference of a circle, you have to multiply the diameter of the circle with pi.(3.14)

First, to get the diameter of a circle you have to multiply the radius by 2.

$10*2=20$

The diameter is 20 centimeters.

Then, multiply the diameter by pi.(3.14)

$20*3.14=62.8$

The circumference is 62.8 centimeters.
