Question

Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm. A) 9π cm3 B) 21π cm3 C) 42π cm3 D) 63π cm3

Answer 1

Option (D) is correct.

The volume of given cylinder is 63π cm³

Explanation:

Given : a cylinder with a radius of 3 cm and a height of 7 cm.

We have to find the volume of the given cylinder.

Consider the given cylinder with a radius of 3 cm and a height of 7 cm

We know,

Volume of cylinder =
`\pi r^2h`

Where, r is radius

and h is height

Substitute, h = 7 and r = 3

We have,

Volume of cylinder =
`\pi \cdot (3)^2 \cdot 7`

Simplify, we have,

Volume of cylinder =
`\pi \cdot 9 \cdot 7`

Volume of cylinder =
`63\pi`

Thus, The volume of given cylinder is 63π cm³
