Answer:

The circumference of the circle is 62.8 mm.

Step-by-step explanation:

We must first know the formula for finding the circumference.

C = dπ

Let's plug in our diameter. We will use 3.14 for pi.

C = (20)(3.14)

Multiply the numbers together.

C = 62.8

So, the circumference of a circle with a diameter of 20 mm is 62.8 mm.
