### How many inches are in a circle?

Pi, also known as π, is one of the most important constants. A ratio of a circle's circumference to its diameter, pi never terminates but is often given as just 3.142. You can calculate the circle's circumference in inches with pi in the equations circumference = 2 * radius * pi and circumference = diameter * pi.

### What is the area of an 8 foot circle?

What is the area of a circle with a DIAMETER of 8 feet (radius of 4 feet)? How big is a 8 foot circle? The area of a circle is pi times the square of its radius. The radius is half the diameter. The diameter of a circle is the distance from one edge to the other, passing through the center.
