WebJan 16, 2024 · Area of a circle using circumference If you have no idea what the radius or diameter is, but you know the circumference of the circle, C, you can still find the area. Area and circumference formula Circumference (the distance around the circle) is found with this formula: C=2\pi r C = 2πr WebThe formula for finding the circumference includes the diameter, and looks like this: C = \pi π d. To make this easier, we can also find the circumference if we know the radius of a circle. We know that the diameter is equalled to 2r (2 times the radius), so in other words, the formula for a circle's circumference is: C = 2 \pi π r.
