the circumference of a circle can be found using the formula c = 2πr. which is an equivalent equation solved for r? r = cπ r = c(2π) r = \\frac{c}{2π} r = \\frac{2π}{c}

the circumference of a circle can be found using the formula c = 2πr. which is an equivalent equation solved for r? r = cπ r = c(2π) r = \\frac{c}{2π} r = \\frac{2π}{c}

Answer

Explanation:

Step1: Isolate r

Given $C = 2\pi r$, divide both sides by $2\pi$. $r=\frac{C}{2\pi}$

Answer:

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