Chapter 14 - Mensuration

Example 5. A hemispherical bowl of contains some liquid. This liquid is to be filled into cylindrical shaped bottles each of diameter 5cm and height 6cm. Find the number of bottle necessary to empty the bowl.

Solution:- Inner radius R of the bowl = 30/2 = 15cm

Inner radius r of the bottles = 5/2cm

Height, h of bottles = 6cm

Let no. of bottles required be x

Vol of x bottle = vol. of hemisphere

No. of bottles = 60
