Question

A cylinder can hold three golf balls one directly above the other. If the radius of a golf ball is 2cm, what volume of the can is occupied by air outside the golf balls?

Answer 1

50.27 cm cubed

Step-by-step explanation:

First you find the volume of the can with the formula
V=Pie(r^2)(h)
Height comes from multiplying the golf ball’s diameter (radius times 2) by 3 because they are spheres stacked on each other.

Then you find the volume of one golf ball with the formula
V=4/3(pie)(r^3)
Then multiply that answer by 3 since there are three golf balls.

Once you get those two answers, subtract the volume of the cylinder by the volume of the golf balls and you will get the answer for the space in between the cylinder and golf balls.
