civil war cannonballs were made out of cast iron. A collector found a set of three cannonballs for sale at an auction. The balls had diameters 4.52 inches, 4.346 inches, and 3.908 iches respectively. Find the total volume of cast iron contained in the three civil war cannonballs.
The given cannonballs has the diameters of 4.52 inches, 4.346 inches and 3.908 inches.
The volume of the sphere is ,
Since the given balls are in diameter, divide all the diameter by 2 to obtained radius of the corresponding balls.
Thus, the radius of the three balls are,
Obtain the volume of the three ...
