Okay, here we have this:
Considering the provided cone, we are going to calculate the requested volume, so we obtain the following:
So to calculate the volume of the oblique cone, we will substitute in the following formula:
Volume=(π*radius^2*height)/3
Volume=(π*(6ft/2)^2*4ft)/3
Volume=(π*9ft^2*4ft)/3
Volume=(π*9ft^2*4ft)/3
Volume=(36π ft^3)/3
Volume=12π ft^3
Finally we obtain that the volume of the cone is 12π cubic ft.
