Answer:

With 3 stacked balls, the cylinder diameter is the same as the ball's diameter so that is 4.7 cm.

The height of the cylinder is 3 x diameter of the ball = 4.7*3 = 14.1 cm.

Next we need to know the volume of a cylinder. This is calculated by finding the area of the base times the height.

The base area is pi*radius^2 = 3.14*(4.7/2)^2 = 17.35 cm^2 (rounded).

Now multiply by the height to get the volume = 17.35 * 14.1 = 244.63 cubic cm.
