If a sphere has a diameter of 12 units, what is the volume of half of the sphere?

see explanation

Step-by-step explanation:

The volume (V) of a sphere is

V = πr³ ( r is the radius )

here diameter = 12, hence radius = 6

The volume of half of the sphere is

V = × πr³

  = πr³

  = π × 6³

  = π × 216 ← cancel 3 and 216

  = 2π × 72

  = 144π units³ ← exact value

 ≈ 452.39 units³ ( to 2 dec. places )
