Tennis Balls
I was on my way to hit the courts when I came across a tennis ball along with a can of three tennis balls. I remembered a math problem with a sphere and a cylinder and comparing their volumes. So I decided to insert the image into gsp and use geometry in my real life. I used the formula for the volume of a cylinder and the formula for the volume of a sphere and found that the volume of the ball was around 3 cm cubed and the volume of the cylinder was around 13 cm cubed. Meaning that the space in between the balls would account for about one extra ball. (~WM5)
