WebApr 23, 2024 · How do you measure inches in a circle? Space and Astronomy 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. WebTask 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. …
