Answer:

a) 9

b) 21.2 cm^3

Step-by-step explanation:

a) the balls have a diameter of 3, so 3 balls together = 3 * 3 =9, that is height.

b) volume of ball =  4/3 πr³ = 4/3 * π * 1.5^3 =14.137 cm^3

of 3 balls  = 14.137 cm^3 * 3 = 42.411 cm^3

volume of cylinder = =πr^2h = =π * 1.5^2 * 9 =63.6 cm^3

so empty space = 63.6 cm^3 - 42.411 cm^3 = 21.2 cm^3
