Question

The volume, in cubic feet, of a right cylindrical silo of height and radius is
`V = \pi r^2h` The height of the silo is h(r) = 3.5r. Which statements are true regarding the functions described?

A. To get a volume of 100 cubic feet, the radius must be 2 feet.


B. The domain of
`V(h(r))` is restricted to values of r greater than 0.


C. The output of V is the input of h


D.
`V(h(r)) = 3.5\pi r^3`


E. The volume depends on the radius of the cylinder

Answer 1

1. The domain of
`V (h(r))` is restricted to values of r greater than 0.

2.
`V(h(r)) = 3.5\pi r^3`

3. The volume depends on the radius of the cylinder
