Hello again,

$\displaystyle V=\frac{4}{3}\pi r^3$

Multiply both sides by**3**

$\displaystyle 3V=4\pi r^3$

Divide by $\displaystyle 4 \pi$

$\displaystyle \frac{3V}{4 \pi}=r^3$

Take cube root of both sides and use symmetric property of equality

$\displaystyle r=\sqrt[3]{\frac{3V}{4 \pi}}$ - Nov 30th 2008, 09:16 PMmagentaritaok..........
