Given:

The radius, r=4x

The height,

h=21xy^2

To find the volume of the cone:

The volume of the cone formula is,

V=\frac{1}{3}\pi r^2h

Substitute the values of r and h in the above formula we get,

\begin{gathered} V=\frac{1}{3}\pi\times(4x)^2\times21xy^2 \\ =\frac{1}{3}\pi\times16x^2\times21xy^2 \\ =\pi\times16x^2\times7xy^2 \\ =112\pi x^3y^2 \end{gathered}

Hence, the volume of the cone is

V=112\pi x^3y^2

Thus, the correct option is option D.

Answer:

  (b)  36.56 ft

Step-by-step explanation:

The perimeter is the total of the circumference of a 4 ft circle and two lengths that are 12 ft.

The circumference is given by ...

  C = πd

  C = (3.14)(4 ft) = 12.56 ft

Adding the 24 ft of straight sections, we find the total perimeter to be ...

  P = 12 + 12 + 12.56 = 36.56 . . . feet
