Answer :
The volume of the right cone whose height be 9 cm and the base area be 10π cm² is 300π cm³. The correct option is D.
What is Geometry?
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
We know that the volume of the right cone is given as
[tex]\rm V = \dfrac{1}{3} *A* h[/tex]
where A is the area of the base and h be the height of the cone.
The area of the base circle will be
[tex]\rm A = \pi \ 10^2\\\\A = 100 \pi[/tex]
Then the volume of the cone will be
[tex]\rm V = \dfrac{1}{3} *100 \pi*9\\\\V = 300\pi[/tex]
Thus, the volume of the right Cone is 300π cm³.
