Question

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)
○ r = c/2π
○ r = c/π
○ r = 2πc
○ r = c/π2

Explanation:

Step1: Start with the formula

The formula for the circumference of a circle is $C = 2\pi r$.

Step2: Isolate the radius

Divide both sides of the equation by $2\pi$. So, $r=\frac{C}{2\pi}$.

Answer:

$r=\frac{C}{2\pi}$
