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

  • Math -

    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.
