please answer part one and two

A graduated cylinder is filled to the 40.00mL mark with a mineral oll. The masses of the cylinder before and after the addition of the mineral oll are 124.966 g and 159.446g, respectively. In a separate experiment, a metal ball bearing of mass 19.868g is placed in the cylinder and the cylinder is again filled to the 40.00mL mark with the mineral oul, The combined mass of the ball bearing and mineral oil is 50.952g. Calculate the density and radius of the ball bearing. Part 1 of 2 Be sure your answer has the comect number of significant digits, Density of the basi bearing =cm3g Part 2 of 2 Be sure your answer has the correct number of significant digits. Radius of the ball bearing =cm
