Answer:

[tex]\large\boxed{C)\ V=\dfrac{1}{3}\pi r^2h}[/tex]

Step-by-step explanation:

There is a circle in the base of the cone. The formula of an area of a circle is:

[tex]A=\pi r^2[/tex]

Therefore [tex]B=\pi r^2[/tex]

Substitute to [tex]V=\dfrac{1}{3}Bh[/tex]:

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
