The volume of a cone with a radius of 7 cm is [tex]$147 \pi$[/tex] cubic centimeters. Which expression can be used to find [tex]$h$[/tex], the height of the cone?

A. [tex]147 \pi=\frac{1}{3}(7)(h)^2[/tex]

B. [tex]147 \pi=\frac{1}{3} \pi \left(7^2\right)(h)[/tex]

C. [tex]147 \pi=\frac{1}{3} \pi sh[/tex]

D. [tex]147 \pi=\frac{1}{3} \pi(7)(h)[/tex]

Answer :

The formula for the volume of a cone is

[tex]$$
V = \frac{1}{3}\pi r^2 h.
$$[/tex]

Given that the volume is [tex]$147\pi$[/tex] cubic centimeters and the radius is [tex]$7$[/tex] cm, we substitute these values into the formula:

[tex]$$
147\pi = \frac{1}{3}\pi (7^2)h.
$$[/tex]

Notice that [tex]$7^2 = 49$[/tex], so the equation becomes

[tex]$$
147\pi = \frac{1}{3}\pi (49) h.
$$[/tex]

Since [tex]$\pi$[/tex] appears on both sides of the equation, it can be canceled out, leaving

[tex]$$
147 = \frac{1}{3}(49)h.
$$[/tex]

Thus, the expression that correctly represents the volume of the cone in terms of [tex]$h$[/tex] is

[tex]$$
147\pi = \frac{1}{3}\pi (7^2)h.
$$[/tex]

Among the options provided, the expression that matches this equation is option 2.
