Question

Solve the equation x = {rrº for r. A. r= 73.2 – 27 5 B. r = C. r = D. r = 3.2 (27)

Answer 1

The given equation is

2/3 x pi x r^3

$\begin{gathered} Multiply\text{ x }by\text{ 3 and divide by 2pi. we have} \\ \frac{3x}{2\pi}=\text{ }r^3 \\ \text{Taking the cube root of both sides of the equation, we have} \\ r\text{ = }\sqrt[3]{\frac{3x}{2\pi}} \end{gathered}$

Thus, the correct option is C
