## How do you find the circumference?

**How to find the circumference of a circle:**

- The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
- If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
- If you know the radius, the diameter is twice as large.

## How do you figure out diameter from circumference?

Solve the equation for the diameter of the circle, d= C/π. In this example, “d = 12 / 3.14.” or “The diameter is equal to twelve divided by 3.14.” Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches.
