maksim [4K]

Answer:

$\huge\boxed{\sf Volume = 16728.8 \ units^3}$

Step-by-step explanation:

Diameter = 22 units

Radius = 11 units

$\rule[225]{225}{2}$

$\sf Volume = \frac{4}{3} \pi r^3\\\\Volume = \frac{4}{3} (3.14)(11)^3\\\\Volume = \frac{4}{3} (3.14)(1331)\\\\Volume = \frac{4}{3} (4184.5)\\\\\bold{Volume = 16728.8 \ units^3}$

$\rule[225]{225}{2}$
