Answer:
The radius is 11 / π
Step-by-step 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
