Answer: Option C.

Step-by-step explanation:

You must use the formula for calculate the volume of a cone, which is shown below:

V_\frac{1}{3}r^2h\pi

Where <em>r</em> is the radius and <em>h </em>is the height.

Based on the figure attached:

r=3in\\h=7in

Substitute these values into the formula for calculate the volume of a cone, then the result is:

V_\frac{1}{3}(3in)^2(7in)\pi

V=65.97in^3≈66in³
