Question

1. the formula c = πd can be used to find the circumference of a circle, c, given the diameter, d. given c, write the equation that finds d. d = c/π d = π/c d = cπ d = πc

Explanation:

Step1: Isolate d in formula

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

Answer:

$d=\frac{C}{\pi}$
