Question

Choose the equivalent form of the given formula for lateral area of a cone. $\mathrm{A}=\pi \mathrm{rs}$

A) $s=\frac{\pi \mathrm{A}}{\mathrm{r}}$

B) $\mathrm{r}=\frac{\pi \mathrm{A}}{\mathrm{s}}$

C) $r=\frac{A}{\pi s}$

D) $\mathrm{s}=\frac{\mathrm{r}}{\pi \mathrm{A}}$

Quizplus · Accepted Answer

To solve for $r$, you rearrange the formula $A=\pi rs$ to isolate $r$, resulting in $r=\frac{A}{\pi s}$.
