How do you find the circumference of each circle?

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

What is the circumference of a 3in circle?

If the diameter is 3 inches, then the circumference would be 3π . If you are not allowed to use calculators, most instructors recommend using 3.14 as the π value and calculating manually.

How do you find circumference with area?

The formula C = 2√πA is designed to find a circle’s circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.
