Answer 1

Answer:

The volume of the sphere is 972π mm³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 9mm

π = pi

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * π * (9mm)³

V = π * ⁴⁄₃ *729mm³

V = π * 972mm³

V = 972π mm³

The volume of the sphere is 972π mm³
