Question 23 Mensuration Exercise 17.3

A hemispherical bowl has a radius of 3.5 cm. What would be the volume of water it would contain?

Solution:

The space that a hemisphere takes up is referred to as its volume. The volume of a thing determines how much space it takes up. Half of a whole sphere, a hemisphere is a 3D object. As a result, a hemisphere's volume is equal to half that of a sphere.

Given radius of the hemispherical bowl, r = 3.5 cm = 7/2 cm

Volume of the hemisphere = (2/3)π r3

= (2/3)×(22/7)×(7/2)3

= 11×49/6

= 539/6

= 89\ \frac{5}{6}\ cm^3

Hence the volume of the hemispherical bowl is

89\ \frac{5}{6}\ cm^3
