volume = 4500

use pi = 3.14

find r

 

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