How do you measure inches in a circle?

You can calculate the circle’s circumference in inches with pi in the equations circumference = 2 * radius * pi and circumference = diameter * pi. Locate the circle’s center, and measure the length from its center to a point on its edge to find the radius. For an example, suppose the measurement is 5 inches.
