To rearrange the formula for the circumference of a circle, \( C = 2\pi r \), to solve for the radius \( r \), you would divide both sides of the equation by \( 2\pi \):
\[ r = \frac{C}{2\pi} \]
So 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)
