$V = 4.5 π m^{3}$ $V=4.5 pi " m"^3$

"in terms of $π$ $pi$ " means that we leave $π$ $pi$ in it's symbolic form.

So, to solve, plug the given value of $r$ $r$ into the Volume equation:

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

$V = \frac{4}{3} π {(1.5 m)}^{3}$ $V=4/3 pi (1.5"m")^3$

$V = \frac{4}{3} π (3.375 m^{3})$ $V=4/3 pi (3.375 "m"^3)$

$V = 4.5 π m^{3}$ $V=4.5 pi " m"^3$
