A hemispherical bowl of internal diameter

36 cm

contains liquid. This liquid is to

be filled in cylindřical glasses of

diameter

6cm and

of

height

6cm. Find the

number of

glasses that can be filled

Answer: 72 bottles

Given,

internal diameter=36cm

internal radius=36/2=18cm

volume of bowl=2/3 πr³

=2/3 (22/7) (18³)

=2*22*18³/7*3

=12219.4cm³

volume of bottle=πR²h

=22/7 (3²) (6)

=22*9*6/7

=169.7cm³

no. of bottles required=12219.4/169.7

=72.23=72 bottles approx
