Best Answer

Circumference = Pi * D (the diameter)

Therefore D = Circumference / Pi

Naturally all circles have a circumference, but if this value is known then we can find the diameter by dividing this value by Pi. (Note: Pi is a special number and we can only ever use an approximation to its value.)

PI times the DIAMETER

The formula for the circumference of a circle is pi * diameter or (2 radius.)

The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.

circumference of a circle = 2*pi*radius or pi*diameter

pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
