What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?

Answer 1

The formula for the volume of a hemisphere is V = (2/3)πr^3, where r is the radius.

Plugging in the given radius of 3 cm:

V = (2/3)π(3)^3
V = (2/3)π(27)
V = 18π

Now, rounded to the nearest tenth, the volume of the hemisphere is approximately 56.5 cubic centimeters.
