        How to Find the Circumference of a Circle - A Step-by-Step Guide

        The formula for the circumference of a circle is π times the diameter because it is a constant relationship that has been observed and measured for centuries. The value of π is approximately 3.14, and it is used to calculate the circumference of a circle.

      1. Fact: The circumference of a circle is approximately 3.14 times the diameter.

        2. The diameter is the distance across the circle passing through its center, while the circumference is the distance around the circle.

  • Step 3: Calculate the circumference. Plug in the values for r or d into the formula and multiply by π (approximately 3.14). For example, if the radius is 4 inches, the circumference would be C = 2π(4) = 8π ≈ 25.12 inches.
