The circumference of a circle is equal to d(pi) where d is the diameter of the circle and pi is, well, pi.
In case you do not know what pi is, it is an irrational number roughly equal to 3.14159265358979... that is all I remember. If you are still confused, check "circumference" on wikipedia, the free encyclopedia.
Circumference of the circle: 48*pi = 150.8 inches rounded to the nearest tenth
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
