A wheel is in the shape of a circle. The formula for the circumference of a circle is 2πr where r is the radius. But, the diameter of a circle is twice the radius so this equation can be written, Circumference = πd where d is the diameter. The Circumference is therefore π times as big as the diameter, π = 3.142 or 22/7 approx.
The circumference of a 34mm circle is: 107 mm
The circumference of this circle is about 14.45 units.
The circumference is the length around the outside of the circle. The circumference is equal to 2pieR (2xPiexRadius)
A circle has the radius of 27.7 cm what is the approximate circumference of the circle? The circumference is approx. 174 centimeters.
