A juice seller was serving his customers using glasses. The inner diameter of the cylindrical glass was 5 cm, but the bottom of the 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.

Text Solution

Verified by Experts

Apparent Capacity=`pir^2h`
=`22/7*(5/2)^2*10`
=`1.57*125`
actual Capacity=approve capacity-`2/3pir^3`
=`1.57*125-2/3*3.14*(5/2)^3`
=`163.54 cm^2`.
