Best Answer

Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14

the formula for the circumference of a circle is pi*diameter. the diameter is 2*radius so if 1.5 is the radius, 3 is the diameter plug 3 into the formula... circumference=3.14*3 circumference=9.42

Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.

The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.

Circle's circumference = 2*pi*radius or diameter*pi

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.

diameter = circumference / pi diameter = radius * 2
