Given the formula for the circumference of a circle, C = 2pi*r how would you rearrange the formula if you were interested in finding the radius of the circle? (1 point) r = 2pi*C; r = C/(2pi); r = C_{pi}/2; r = C/pi

Answer 1

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 by \( 2\pi \).

So, the formula for the radius would be:

\[ r = \frac{C}{2\pi} \]

The correct answer is:

r = C/(2pi).
