toy rubber balls are packaged in a circular cylinder that holds 3 balls.
the diameter of each ball is 5.9 cm.
what is the volume of the empty space left in the cylinder?
:
The height of the cylinder: 3 * 5.9 = 17.7
Radius of the balls: 5.9/2 = 2.95
:
Empty Vol = Cylinder vol - 3 balls vol
V = %28pi%2A2.95%5E2%2A17.7%29 - %283%284%2F3%29%2Api%2A2.95%5E3%29
:
V = 431.913 - 322.608
:
V = 109.3 cu/cm of empty space
