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

Answer

Answer:

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

Explanation:

Step1: Isolate the variable $r$.

Given $C = 2\pi r$. Divide both sides by $2\pi$.

Step2: Simplify the equation.

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