If the circumference of a circle is 12 cm the radius is: 1.91 cm

The circumference of a circle with a radius of 12 meters is: 75.4 meters (r x 2 x Pi = circumference).

Its circumference is: 75.4 inches.

Circumference of the circle if the radius is 12 inches is 2*pi*r = 24*pi = 75.398

A circle with a radius of 6 inches has a circumference of 37.7 inches.

The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.

circumference = 2 x π x radius ⇒ radius = circumference ÷ (2π) = 24π ÷ 2π = 12 units.
