Question: Write a program to read the thickness, density, and outside radius of a hollow ball and to calculate its volume and the mass. Starting with a value 0.2 cm, run your program several times to find the largest wall thickness of a copper ball (density = 0.0089 kg/cm3 ) with an outside radius of 50.0 cm that will float in water. (For the ball to float, its volume must be at least 1000 times its mass.)
