If the radius of the circle is 8 cm the circumference is: about 50.27 cm (r x 2 x pi = circumference).
A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
Circumference = πd diameter = 2 x radius
The circumference of any circle = 2*pi*radius or diameter*pi which in this case would be in cm
circumference of a circle = 2*pi*radius or pi*diameter
