A glass tank is 25cm long, 20cm wide, 30 cm high and contain water.The surface of the water is 5 cm below the top of the glass tank. After solid metal spherical ball B1 has carefully been placed into the tank, the surface of the water is 3cm below the top of thetank.
1) Calculate the volume of the ball
2) Calculate the radius of the ball, leave your answer in terms of "pie" and a surd if necessary
3) Suppose the radius of a second solid metal ball, B2, is half the radius of ball B1. Suppose ball B2 was put into the tank of water instead of ball b1. Would the surface of the water be 4cm below the top of the tank. Explain your answer
