Question

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

Answer 1

heya it's Aastha....

Volume of hemisphere = 2/3 pie r3

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

Volume = 2/3 * 22/7 * 18 * 18 * 18

Volume = 256608 / 21

Volume = 12219.42857 cm3

Volume of Cylinder Bottle = pie * r * r * h

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 bottele

Bottles Required = 12219.42857 cm3 / 169.714 cm3

Bottles required = 72
