Question

What is the exact volume of the cone? (height is 9 cm, the radius is 15 cm)

Answer 1

Answer:

675pi

Step-by-step explanation:

The volume of a cone is $\frac{h\pi r^2}{3}$, so we can plug in the values to get 225*9/3 times pi, or 675pi.

Answer 2

Answer:

$675\pi\ cm^3$

Step-by-step explanation:

The volume of the cone can be calculated using the formula

$V_{cone}=\dfrac{1}{3}\pi r^2h.$

In you case,

$r=15\ cm,\ h=9\ cm,$

then the exact volume of the cone is

$V_{cone}=\dfrac{1}{3}\pi\cdot (15)^2\cdot 9=675\pi\ cm^3.$
