Answer:

The radius is 11 / π

Explanation:

Given:

  • Circle has a circumstance of 22cm
  • want: radius

Circumstance Formula:

C = 2πr

  • C = circumference
  • π = constant of pi
  • r = radius

we are given C and want to find R

22cm = 2πr

divided both sides by 2π

22cm / 2π = 2πr / 2π

11 / π = r

decimal form: 3.5014
