Your lab develops a synthetic compound that is extremely light but very durable. You test it by making a solid ball with a radiu

Maksim231197 [3]

The volume of a spherical shaped object is given by

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

Given that the <span>solid ball has a radius of 20.0 millimeters, the volume of the solid ball is given by

$V= \frac{4}{3} \pi(20)^3\approx33,510mm^3$

Therefore, the </span><span>closest to the volume of the synthetic compound ball, in cubic millimeters is 33,500 cubic milimeters.</span>
