How many cylindrical glasses of diameter 8 cm and length 10 cm are required to fill a cylindrical bottle of radius 10 cm and height 32 cm?
Given, Solid: Cylinder
Length of glass, h=10 cm
Radius of glass, r=82=4 cm
Length of bottle, H=32 cm
Radius of bottle, R=10 cm
Let, number of glasses required to fill bottle be n
Volume of water bottle=n×Volume of glassnπr2h=πR2Hnr2h=R2Hn×42×10=102×32n=100 × 3216 ×10=20
Number of glasses required to fill bottle are 20.
