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.
