Write an expression in factored form to represent the volume in the canister not occupied by the tennis balls.

olya-2409 [2.1K]

Answer:

$\implies V=\pi r^2(h-4 r)$

Step-by-step explanation:

Volume of the canister LESS the volume of 3 tennis balls:

$V=\pi r^2h-3\left(\dfrac43\pi r^3\right)$

Expand brackets:

$\implies V=\pi r^2h-4\pi r^3$

Factor:

$\implies V=\pi r^2(h-4 r)$
