A cone shaped paper cup has a height of 7 inches and a diameter of 5 inches. What is the volume of the cone? Round to the nearest hundreth

recall that volume of cone is given by
V = (1/3)*pi*(r^2)*h
where
r = radius which is half of diameter
h = height
and pi = constant equal to 3.14
substituting,
V = (1/3)*3.14*[(5/2)^2]*7
now solve for V.
