Answer:

60π

Step-by-step explanation:

If the circle has radius of 30 units, substitute r=30 into the formula C = 2πr.

C = 2π(30)

C = 60π

To find the circumference of the circle shown here, let's start with writing the formula down.

Circumference = 2\pir

We have to divide 60 by 2 because the radius is always half the diameter. Now, we can plug in 30 for r in the formula.

Now we have

circumference = 2\pi30.

This equals 60\pi.
