What is the volume of a hemisphere with a diameter of 54.8 in, rounded to the nearest tenth of a cubic inch?

Step-by-step explanation:

43083.4 in

3

The volume of the hemisphere is 43083 in³

Step-by-step explanation:

The hemisphere is half a sphere, in order to calculate it's volume we need to calculate the volume of a sphere with the same radius and divide it by 2. We have:

Volume = [ (4/3) * pi*r³]/2

Where r = d/2 = 54.8/2 = 27.4 in. Applying this to the equation we have:

Volume = [ (4/3) * pi * (27.4) ³]/2 = 43083 in³

The volume of the hemisphere is 43083 in³
