Find the volume of a cone whose height is 7.5cm and the base diameter is 7cm pi=22/7

92.64 cm^3 (it should be smaller if using actual pi, 22/7 is larger than pi)

Step-by-step explanation:

The equation for the volume of a cone is 1/3 (pi*h*r^2) So, first we need to find the radius, which is diameter over 2, so the radius is 3.5 cm. Now we know all of the variables so we can plug in to solve.
