Question

Solve the equation x = 5/3 (pie) (r^3) for r.

Answer 1

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

$x = \frac{5}{3} \pi r^{3}$

Multiply each side by $\frac{3}{5}$, then divide by $\pi$ (pi)

$\frac{3x}{5\pi } = r^{3}$

Now, take the cubed root of both sides.

$\sqrt[3]{\frac{3x}{5\pi } } = r$

^^ That is the answer.
