Formula. The formula used to calculate the circle radius is: r = C / (2 · π) Symbols. r = Circle radius. C = Circle circumference. π = Pi = 3.14159…. Circumference of Circle. Enter the circumference which is the total length of the edge around the circle, if it was straightened out.

To calculate the circumference of a circle, use the formula **C = πd**, where "C" is the circumference, "d" is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter.

**Diameter** Which is the circle's 'width'. The **diameter** is two times the **radius**. See **diameter** of a circle. Circumference The circumference is the distance around the edge of the circle. See Circumference of a Circle for more.

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. You can read more about circumference in this WikiPedia article - Circumference.
