C=pi*d
circumference equals pi times diameter.
Which means 3.14 (which we will use for pi) times 22 equals 69.08 in.

If radius = 22 inches then circumference = 138.2 inches. If diameter = 22 inches then circumference = 69.1 inches. Please help us to help you by being clearer when you ask your question.
The circumference of a circle with a diameter of 22 is 22 times pi or approximately 69.08.
The circumference is about 22 units.
Circumference of a circle is equal to 2(pi)r with r being the radius, or (pi)d with d being the diameter. If we use (pi)d, with d being equal to 7 and (pi) being equal to 3.14159, we get that the circumference is 21.9911485751 inches. This can be rounded to 22 inches.3.14159 * 7in = 21.9911485751in
