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.
