C = 2 × π × r

Or equivalently: C = π × d (where d is the diameter)

Where:

C = Circumference

π ≈ 3.14159

r = radius

d = diameter (2r)

Find the circumference of a circle with radius 7.

What is circumference?

Circumference is the distance around the edge of a circle — essentially the perimeter of a circle.

What is the relationship between circumference and diameter?

The circumference divided by the diameter always equals π (pi). This is actually the definition of pi: C/d = π.
