Question

A hemispherical bowl of internal diameter 36 cm contains a liquid.this liquid is to be filled in cylindrical bottles of radius 3 cm and height 6cm.how many bottles are required to empty the bowl?

Answer 1

Hii There!!
Since, Volume of hemisphere = 2/3×π×r3

Given, Diameter = 36 cm , Radius = 36 / 2 = 18 cm

Volume = 2/3 × 22/7 ×18 × 18 × 18

=)256608 / 21

=)12219.42857 cm3

Volume of Cylinder Bottle = πr2h

Given, Radius = 3 cm and height = 6 cm

Volume = 22/7 × 3×3× 6

Volume = 1188/7

Volume = 169.714 cm3

Bottles Required =)
Volume of hemispherical bowl / Volume of Cylindrical bottle

Bottles Required = 12219.42857/ 169.714

Hence, No. of Bottles required = 72.
