what is "4/3 3.14 r^3

volume = 4500

use pi = 3.14

find r

$$\\Volume=\frac{4}{3}\pi r^3\\\\ 4500=\frac{4}{3}*3.14* r^3\\\\ 4500\times \frac{3}{4}=\frac{4}{3}*\frac{3}{4}*3.14* r^3\\\\ 4500\times \frac{3}{4}= 3.14* r^3\\\\ 4500\times \frac{3}{4}\div3.14= 3.14* r^3 \div 3.14\\\\ 4500\times \frac{3}{4}\div3.14= r^3 \\\\ r^3=4500\times \frac{3}{4}\div3.14 \\\\ r=(4500\times \frac{3}{4}\div3.14)^{1/3} \\\\$$

You can finish this on the site calc on the home page :)

This is a formula for the volume of a sphere.

yes,

sry but the quetion is "if the volume of a given sphere is 4500 3.14, detemine the radius of a sphere.
