To rearrange the formula for the circumference of a circle \( C = 2\pi r \) in order to solve for the radius \( r \), you would divide both sides by \( 2\pi \):
\[ r = \frac{C}{2\pi} \]
Therefore, the correct response is:
r = C / 2π
Given the formula for the circumference of a circle, C=2πr , how would you rearrange the formula if you were interested in finding the radius of the circle? (1 point) Responses r=Cπ/2
r=C/π
r=2πC
r=C/2π
