Answer:
radius = C / 2π :)
Step-by-step explanation:
The circumference is 2πr, right?
Let's put this information into an equation :)
C = 2πr
Now, we can simply divide both sides by 2π here to isolate r (the radius) by itself, because that's what we want! (Something equal to the radius)
C / 2π = r
There's your answer! :)
Subtract

c
2c from both sides of the equation
