Question

What is the formula to find the height of the tank consisting of a circular cylinder with a hemisphere attached on either end?

(a) Radius of the cylinder + 2(height of the hemisphere)

(b) Height of the cylinder + 2(height of the hemisphere)

(c) Radius of the cylinder + 2(radius of the hemisphere)

(d) Height of the cylinder + 2(radius of the hemisphere)

The question was asked in an online quiz.

This is a very interesting question from Surface Area and Volume of Combination of Solids in section Surface Area and Volumes of Mathematics – Class 10

Answer 1

Right answer is (d) Height of the cylinder + 2(radius of the hemisphere)

The explanation: To find the height of the tank consisting of a circular cylinder with a hemisphere attached on either end requires the height of the cylinder and radius of the hemisphere.

Height of the tank = height of the cylinder + 2(radius of the hemisphere)
