Find the volume of a cone with a radius of 30 and height of 7a. 6300πb. 2100πc. 189,000πd. 210π

Sagot :

To get the volume of a cone, we have the formula below:

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

where r = radius and h = height

In the question, radius = 30 units while height = 7 units. Let's plug these values to the formula above.

[tex]\begin{gathered} V=\frac{\pi r^2h}{3}=\frac{\pi(30)^2(7)}{3} \\ V=\frac{\pi(900)(7)}{3} \\ V=\frac{6300\pi}{3} \\ V=2100\pi \end{gathered}[/tex]

The volume of the cone is 2100π.
