The volume of the sphere is $288 \pi$ cubic meters.

Explanation:

Given that the radius of the sphere is 6 m

We need to determine the volume of the sphere.

<u>Volume of the sphere:</u>

The volume of the sphere can be determined using the formula,

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

Substituting the value $r=6$ in the above formula, we have,

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

Simplifying the values, we get,

$V=\frac{4}{3} \pi (216)$

$V=\frac{864}{3} \pi$

$V=288 \pi$

Thus, the volume of the sphere is $288 \pi$ cubic meters.
