question 4 of 10
solve the formula $c = pi d$ for $d$
a. $d = c - pi$
b. $d=pi c$
c. $d = \frac{c}{pi}$
d. $d=\frac{pi}{c}$

Explanation:

Step1: Isolate the variable d

We start with the formula $C = \pi d$. To solve for $d$, we need to get $d$ alone on one side of the equation. Since $d$ is being multiplied by $\pi$, we divide both sides of the equation by $\pi$.
$\frac{C}{\pi}=\frac{\pi d}{\pi}$

Step2: Simplify the right - hand side

On the right - hand side, $\frac{\pi d}{\pi}=d$ because $\frac{\pi}{\pi} = 1$. So we have $d=\frac{C}{\pi}$.

Answer:

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