Note: Figure is not drawn to scale.

If h = 15 units and r = 5 units, what is the volume of the cone shown above?
Use 3.14 for .
A.
78.5 cubic units
B.
1,177.5 cubic units
C.
235.5 cubic units
D.
392.5 cubic units

Answer 1

Option D.
`392.5\ units^(3)`

Explanation:

we know that

The volume of the cone is equal to

`V=(1)/(3) \pi r^(2)h`

In this problem we have

`h=15\ units`

`r=5\ units`

substitute the values

`V=(1)/(3) (3.14)(5^(2))(15)=392.5\ units^(3)`
