Calculate the area, circumference and radius of circles. Given any 1 known
variable of a circle, calculate the other 2 unknowns. Circle formulas and
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this
formula to find the area of a circle when given the diameter.
This calculator will calculate the area of a circle given its radius, using the famous
formula area = pi x r squared.
With this circle calculator you can find the area of a circle to help with your
Given the radius, use this area of a circle calculator to find the area for any circle.
Note: If you have the diameter of a circle, you can use it to find the area of that
circle. Just plug that value into the formula for the area of a circle and solve.
