Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference.Circumference =πd =3.14159×12=37.69 feetConclusionNow you know how to calculate th
The radius of a circle always equals half of its diameter, so to find the diameter, multiply the radius by two. For example, if you know the radius of a circle is 4 centimeters, work out 4×2=8 The diameter of the circle is 8 centimeters. Find Diameter From Circumference 1. Note th...

the radius, and the fixed point is called the center of the circle. The diameter of a circle is any line segment that passes through the center of the circle and has its endpoints on the circle. You can easily find the diameter of a circle if you know its radius or circumference. ...
the number π, or pi. Pi is defined as being equal to the circumference of a circle — the distance around that circle — divided by its diameter. However, you don't need to memorize this formula when working with π, since it is a constant. The value of π is always the same, ...
