If a diameter of a youth softball is 3.5 and the diameter of an adult softball it's 3.8 inches, what is the approximate difference in their volumes? use 3.14 for π. round to the nearest tenth of a cubic inch.

The answer rounded to the nearest tenth of a cubic inch is 6.3.

The first thing we want to do is find the volume of the softballs. The formula to find the volume of a sphere(softball) is: 4/3 pi r³

r = Radius (which is half of the diameter)

To find the volume of the Youth Softball we would do: 4/3 pi 1.75³. Which is 22.45.

To find the volume of the Adult Softball we would do: 4/3 pi 1.9³. Which is 28.73.

Next we would subtract them both to find the difference, by doing 28.73 - 22.45.

That will give you the difference between the youth and adult softball.
