Question

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

Answer 1

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

`V=(\pi r^2h)/(3)`

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.

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

The volume of the cone is 2100π.
