WebWhichever unit the radius is measured in will also be the unit the circumference is calculated in. You can also calculate the circumference of a circle using the diameter, with the equation C = Π * d. If you only have the diameter of a circle and would still like to use this calculator, you can find the radius by dividing the diameter in half. WebCircumference = 2*Pi*Radius. So, Radius = Circumference/ (2*Pi) Formula/Equation for finding circumference of a circle The formula to find the circumference when radius is given is Radius = Circumference/ (2*π) The formula to find the area when radius is given is Area of circle = π*Radius*Radius In the above formulas, π=3.14159 and R is the radius.
