A juice seller was serving his customers using glasses as shown. The inner diameter of the cylindrical glass was 5 cm. But the bottom of glass had a hemispherical raised portion which reduced the capacity of the glass. If the height of a glass was 10 cm. Find the apparent capacity of the glass and its actual capacity

Answer:
Step-by-step explanation:
Find the volume of the cylinder:
Volume = πr²h
Volume = π(5 ÷ 2)²(10) = 90π cm³
Find the volume of the hemisphere:
Volume = 2/3 πr³
Volume = 2/3 π(5 ÷ 2)³ = 18π cm³
Find the capacity of the glass:
Capacity = 90π - 18π = 72π = 226.08 cm³
Answer: Its actual capacity is 226.08 cm³
