How do you calculate the circumference circle

WebThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159. It was originally defined as the ratio of a circle's circumference to its diameter … WebThe circumference of a circle and the area of a circle have one thing in common: the radius. If I were you I'd do it in two steps: - first calculate the radius using the circumference formula, - then calculate the area using the radius you just calculated :-) Hope that helps!
