four spheres of radius 6cm just fit inside a cylinder calculate the volume inside the cylinder that is empty leave your answers

Alekssandra [29.7K]

Answer:

The volume inside the cylinder is $1152\pi\ cm^3$ .

Step-by-step explanation:

Given : Four spheres of radius 6 cm just fit inside a cylinder.

To find : Calculate the volume inside the cylinder that is empty ?

Solution :

The volume of the cylinder is volume of 4 spheres.

The volume of sphere is $V=\frac{4}{3}\pi r^3$

The radius is 6 cm.

The volume of four spheres is

$V=4\times \frac{4}{3}\times \pi\times (6)^3$

$V=1152\pi\ cm^3$

Therefore, the volume inside the cylinder is $1152\pi\ cm^3$ .
