Geometry

  • Radius: r = d/2
  • Circumference: C = 2πr

Step-by-step explanation:

Step 1: Define

d = 22 in

Step 2: Find r

  1. Substitute:                       r = 22 in/2
  2. Divide:                              r = 11 in

Step 3: Find C

  1. Substitute:                    C = 2π(11 in)
  2. Multiply:                        C = 22π in
  3. Multiply:                        C = 69.08 in
