Then you need to ask yourself "How many ball bearings can I make with the volume of molten metal I have from melting the cone?" Two of the measurements are in centimeters and one is in meters. You need them all in the same units so I'm going to use centimeters. Thus the cone is 500 cm high. The volume of a cone is given by
where r is the radius and h is the height, both in centimeters. Calculate the volume of the cone. The volume of a sphere is given by
where r is the radius in centimeters. Calculate the volume of a ball bearing. How many ball bearings can you make with the volume of metal obtained by melting the cone? Harley
