Answer:
[tex]\frac{C}{2\pi } =r[/tex]
Step-by-step explanation:
Recall to find the circumference of a circle the formula is [tex]C=\pi d[/tex] or [tex]C=2\pi r[/tex]. Since we need r, we will use the second formula for circumference.
We start by solving for r in the Circumference formula. using inverse operations. We divide both sides (as the inverse of multiply) by 2pi.
[tex]C=2\pi r\\\frac{C}{2\pi } =r[/tex].
