Question

A hemispherical bowl has inner diameter 11.2 cm. Find the volume of milk it can hold.

Answer 1

Inner diameter of hemispherical bowl = 11.2 cm 

r = `11.2/2`

= 5.6 cm

To Find: Volume of milk it can hold.

Steps:
Volume of a hemisphere:

V = `2/3` π r³

Substitute r = 5.6 cm and take π = `22/7`

V = `2/3 xx 22/7 xx (5.6)^2` 

(5.6)³ = 5.6 × 5.6 × 5.6

= 175.616

V =  `2/3 xx 22/7 xx 175.616`

V = 367.96 cm³
