To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...
