Question

In the following question, two statements, (i) and (ii), are given. Choose the valid statement.

1. The height and radius of a cylinder are 12 cm and 5 cm respectively. Its volume will be 300 π cm³.
2. Volume of sphere is `4/3πr^3`.

पर्याय

• Only (i)

• Only (ii)

• Both (i) and (ii)

• Neither (i) nor (ii)

Answer 1

Both (i) and (ii)

Explanation:

• Statement (i) is valid because the volume of the cylinder is πr²h = π × 5² × 12 = 300 π cm3. 
• Statement (ii) is also valid as `4/3πr^3` is the correct standard formula for the volume of a sphere.
