Question

What is the formula required to find the height of a solid in the form of a right circular cylinder with a hemisphere at one end and a cone at the other end?

(a) 4793 m^3

(b) 2763 m^3

(c) 2783 m^3

(d) 4783 m^3

I had been asked this question during an interview.

The doubt is from Surface Area and Volume of Combination of Solids in section Surface Area and Volumes of Mathematics – Class 10

Answer 1

The correct choice is (c) 2783 m^3

The best I can explain: To find the height of the solid we require the height of the cone, height of the cylinder and the radius of the hemisphere.

Height of the solid = height of the cone + height of the cylinder + radius of the hemisphere
