A juice seller was serving his customers using glasses as shown in Figure 3. The inner diameter of the cylindrical glass was but bottom of the glass had a hemispherical raised portion which reduced the capacity of the glass. If the height of a glass was , find the apparent and actual capacity of the glass.
Given, the height of the glass
radius of glass
To find = Volume of the shaded region/glass
vol. of glass = [ Vol. of the cylinder - Vol. of homisphere]
Apparent capacity = volume of the cylindrical portion
