Calculating the circumference using the radius. If we have the radius of a circle then to calculate the circumference we multiply pi (∏) by the radius (r) of a circle and then multiply by 2. For the circle above we have a radius (r) of 5cm, so lets calculate the circumference: And...
TL;DR (Too Long; Didn't Read) The formula for the surface area of a circle is _A_ = π_r_2, where _A_ is the area of the circle and _r_ is the radius of the circle. An Introduction to Pi In order to calculate the area of a circle you'll need to understand the concept ...

A circle's diameter and radius are both intimately tied to its circumference, or the distance all the way around the outside of the circle. (Circumference is just a fancy word for the perimeter of any round object). So if you know the circumference, you can calculate the circle's radius...
How to Calculate the Circumference of a Circle? Since circles do not have straight edges like polygons, we cannot measure their boundary length with a ruler. We can find the circumference of a circle by knowing its radius or diameter. The radius of a circle is the distance between the cent...
Circular shapes have the same length from the center to any point on their boundary; that distance is the radius of a circle. If there is no such point on the boundary, the radius is zero. The length of the radius is the same for each point in the boundary. The radius is denoted ...
