Diameter of the ball = 4.2 cm. Radius of the ball = 2.1 cm. 4 2'Z Volume of the ball = x 7x (2.1>3 cm = 38.808 cm. Mass of the ball = density x volume ' = 8.9 x 38.808 g = 345.39 g (approx.)

Diameter = 4.2 cm  , Density = 8.9g/cc3 Radius = 2.1cm  , volume =  4/3 *22/7*2.1
Mass =  Density* Volume =>  Mass =  8.9 * 4/3 * 22/7 * 2.13 =  345.3912 g = 0.345 kg
