Answer:
V = 1250π/3 mm³
V = 1309 mm³
Explanation:
The composite figure is made up of a cylinder with radius 5 mm and two hemispheres of radius 5 mm. The height of the cylinder is
20 mm - 5 mm - 5 mm = 10 mm
The two hemispheres make up a full sphere of radius 5 mm.
V = πr²h + (4/3)πr³
V = π(5 mm)²(10 mm) + (4/3)π(5 mm)³
V = [(25 mm²)(10 mm) + (4/3)(125 mm)³]π
V = [250 mm³ + 500/3 mm³]π
V = 1250π/3 mm³
V = 1309 mm³
