A hemispherical bowl is made of steel 0.25 cm thick. The inside radius of the bowl is 5cm. Find the volume of steel used in making the bowl.
Answer:
Inner radius of a hemispherical bowl = 5 cm
Outer radius of a hemispherical bowl = 5 cm + 0.25 cm = 5.25 cm
Volume of steel used = Outer volume - Inner volume
= 41.282
Volume of steel used is 41.282 cm3
