2. Ajuice seller was serving his customers using glasses. The inner diameter of the cylindrical glass was 5cm, but
the bottom of the glass had a hemispherical raised portion which reduced the capacity of the glass. If the
height of glass was 10cm, find what the apparent capacity of the glass was and what the actual capacity
was. (use = 3.14)

Answer:
163.5 cm³
Step-by-step explanation:
net volume = volume of glass — volume of hemisphere
= πr²h — 2/3 πr³
=πr²(h — 2/3r)
=3.14× 2.5²(10—2/3×2.5)
=3.14× 2.5²×8.33
=163.47cm³ ≈ 163.5cm³
hope this helps
