Answer:
485.9 mm³
Explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
V = (2 / 3) π r³
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
V=π(4)²(7)
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
V = 128π/3 + 112π
= 485.9 mm³
