Question

What is the volume of a hemisphere if the radius of the hemisphere is 3 m?

(a) 135.4 m^3

(b) 56.52 m^3

(c) 120.23 m^3

(d) 105.5 m^3

I had been asked this question in a job interview.

I need to ask this question from Surface Area and Volume of Different Solid Shapes in division Surface Area and Volumes of Mathematics – Class 10

Answer 1

The correct choice is (b) 56.52 m^3

The best I can explain: Radius of the hemisphere = \(\frac {2}{3}\)πr^3

= \(\frac {2}{3}\) × 3.14 × 3^3

= 56.52 m^3
