Question

the equation for the circumference of a circle is c = πd. the variable c represents the circumference and d represents the diameter of the circle. solve the equation for the diameter, d.

Explanation:

Step1: Isolate the variable $d$

Divide both sides of $C = \pi d$ by $\pi$.
$d=\frac{C}{\pi}$

Answer:

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