Answer:

The formula for circumference is: C = 2πr   or   C = πd

Step-by-step explanation:

C = 2πr

(Circumference equals two times pi times radius)

C = πd

(Circumference equals pi times diameter)

Circumference is the distance around a circle.

Diameter is the measure of one side of the circle to the other.

Radius is half of the diameter.
