A circumference of 75.4 units.
Circumference of a circle = 2*pi*radius or diameter*pi Its diameter = circumference/pi
Since Pi is equal to the circumference over diameter, the diameter of a circle is equal to its circumference over Pi. So divide 24 centimeters by 3.14159 to get approximately 7.63943 centimeters.
A circle with a radius of 24 inches has a circumference of 150.8 inches.
