The radius of a cone-shaped tank is 4 feet less than its height. If the height of the tank is (x - 3) feet, the expression below shows the volume of the tank: 1 over 3π (x - 7)2 (x - 3) What does the factor 1 over 3(x - 7) represent?

    4 less than the height would be x-3-4=x-7 and that's 5he radius
