For an art project, Pedro uses clay to make 3 balls, each with a diameter of 4 in. What is the total volume of the 3 balls of clay?

You would need to find the volume of one ball and then multiply it by 3.

To find the volume solve V = (4/3) (3.14) r^3

The radius is half the diameter so r=2

So the volume of one ball is 33.51 and 33.51*3=100.53

The total volume of the three balls of clay is 12 inches because all you have to do is multiply the diameter of the ball to the total number of balls you got and then you would find the volume which is 12 inches
