Question

HELP!!!! Select the correct answer. What is the volume of this cone in terms of ?

Answer 1

Answer:

168.75π cm^3 is your answer.

Volume of a cone is 1/3 πr^2h.

Here, radius is given 7.5cm and height is given 9cm. So by using the formula we get the above answer.

Answer 2

For this case we have that by definition, the volume of a cone is given by:

$V = \frac {\pi * r ^ 2 * h} {3}$

Where:

h: It's the height

r: It is the cone radius

According to the data we have:

$h = 9cm\\r = 7.5cm$

Substituting:

$V = \frac {\pi * (7.5) ^ 2 * 9} {3}\\V = \frac {\pi * 56.25 * 9} {3}\\V = 168.75\pi$

Thus, the volume of the cone is $168.75 \pi \ cm ^ 3$
