    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
