Circle Calculator

Calculate the area and circumference of a circle.

For example, with a radius of 7: $$ \text{Area} = \pi \times 7^2,\quad \text{Circumference} = 2\pi \times 7.$$

Step 1: Enter the Circle’s Radius

Enter the radius of the circle (e.g., 7)

The formulas used are: $$ \text{Area} = \pi r^2,\quad \text{Circumference} = 2\pi r. $$
