To solve this, you need the formula for finding the circumference of a circle, (pi) x diameter. pi = 3.14. Diameter means the length all the way across the circle.

Since our diameter is 48 inches, simply multiply 48 x 3.14. The circumference of our circle is 150.72 inches.

If 48 inches is the length of the radius, or halfway across the circle, simply change the formula to 2(pi) x radius, which gives us 2 x 3.14 x 48, or 301.44 inches.
