The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.

Since the height is 7ft and the radius if 4ft you plug those into the equation and get:

V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B

By definition, the volume of a cone is given by:

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

Where,

r: cone radius

h: height of the cone

Substituting values in the given equation we have:

V = (\frac{1}{3}) * \pi * (4) ^ 2 * (7)

Using this last expression, we can find the volume of the cone.

Answer:

The volume of the cone is given by the following expression:

V = (\frac{1}{3}) * \pi * (4) ^ 2 * (7)
