Question

The diameter is 1 cm. What is the circumference.

Answer 1

3.14

Explanation:

C = pi * d

C = 3.14 * 1

C = 3.14

Answer 2

3.14

Explanation:

To find the circumference of a circle, just use the formula of C=πd. In this case, I'm going to round pi to 3.14. To find the circumference, multiply pi (3.14) by the diameter (1) to get a circumference of 3.14. My work is below!

3.14 x 1 = 3.14
