Question

What the volume of a hemisphere with a radius of 10 cm.

Answer 1

Approximately 418.8790
Hope this helps!

Answer 2

volume of sphere = (4/3)(pi)(radius)^3

hemisphere is 1/2 sphere

therefore

volume of hemisphere = (1/2)(4/3)(pi)(radius)^3
V = (2/3)(pi)(10)^3
V = (2/3)(1000)(pi)
V = 666.67pi cm^3
V = 2094.40 cm^3
