At a Ramzan Mela, a stall keeper in one of the food stalls has a large cylindrical vessel of base radius 15 cm filled up to a height of 32 cm with orange juice. The juice is filled in small cylindrical glasses (see Fig. 13.27) of radius 3 cm up to a height of 8 cm, and sold for Rs 3 each. How much money does the stall keeper receive by selling the juice completely?

Explanation

Number of glass*Volume of juice in each glass=Volume of orange

`n*pi*r^2*h=piR^2H`

`n(3)^2(8)=15^2*32`

`n=100 glasses`

Total Money=No. of glasses*cost

=100*3

=300Rs
