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

Volume of a cylinder is π * r^2 * h
so 3^2 * 7 * π = 9 * 7π = 63π cm^3

The answer is D. 

Answer 2

Answer:

Option (D) is correct.

The volume of given cylinder is 63π cm³

Step-by-step 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
