Answer:

Step-by-step explanation:
the information we have is:
- the radius of the circle in the base:
(u for units)
- and the height of the cone:

to find the volume we need the formula for the volume of a cone:

where r is the radius and h is the height.
Substituting the known values to find the volume:

the volume in terms of
is 
and if we substitute the value of pi:
we get:

Answer:
8. B
