Question

What is the volume of the cone below?

Answer 1

Answer:

The correct answer is option B.  112π units ³

Step-by-step explanation:

Formula

Volume of cone = (πr²h)/3

Where r - Radius of cone and

h - Height of cone

To find the volume of cone

Here radius r = 4 units

Height h = 21 units

Volume = (πr²h)/3

= (π * 4² * 21)/3

= 112π units ²

Therefore the correct answer is option B.  112π units ³

Answer 2

ANSWER

B.

$112\pi \: {units}^{3}$

EXPLANATION

The volume of a cone is calculated using the formula:

$Volume = \frac{1}{3} \pi {r}^{2}h$

where r=4 units is the base radius of the cone.

and h=21 units is the vertical height of the cone.

We plug in the values to get;

$Volume = \frac{1}{3} \times \pi \times {4}^{2} \times 21$

$Volume = 112\pi \: {units}^{3}$
