Question:
The volume of the frustum of a cone is $\frac{1}{3} \pi h\left[r_{1}^{2}+r_{2}^{2}-r_{1} r_{2}\right]$, where $h$ is vertical height of the frustum and $r_{1},
r_{2}$ are the radii of the ends.
Solution:
False
Since, the volume of the frustum of a cone is $\frac{1}{3} \pi h\left[r_{1}^{2}+r_{2}^{2}+r_{1} r_{2}\right]$, where $h$ is vertical height of the frustum
and $r_{1}, r_{2}$ are the radii of the ends.
