Answer:

option 3, 972\pi in^{3}

Step-by-step explanation:

The formula to find the volume of a sphere is \frac{4}{3} \pi r^{3}

where r os the radius

given: diameter = 18in

radius = diameter / 2

radius = 18 / 2

r = 9in

Plug in radius:

\frac{4}{3} \pi (9)^{3}\\\\\frac{4\pi (9)^{3}}{3} \\\\Factor (9)^{3}: (3)^{6}\\\\\frac{(3)^{6} * 4\pi }{3} \\\\

cancel common factor: 3

3^{5} * 4\pi \\3^{5} = 243\\243 * 4\pi\\972\pi
