Real-Life Math

You are a mycologist engaged in research. You have recently gone for a walk in the woods and encountered a giant puffball. Giant puffballs can grow to be quite large. Some are more than a meter in diameter. And when they are pure white inside, they are both edible and delicious.

However, your interest in this giant puffball is for research purposes. You will have to go mushrooming another day if you want to cook one for dinner!

You carry the puffball back to the lab and prepare to measure it. Measuring it carefully, you determine that your giant puffball is exactly 1.2 meters in diameter.

The giant puffball bears its spores internally. You want to know the length of each spore. They are all identical in size, so if you can measure one, you will know the size of all.

Carefully, you cut it open and place a section under your high-powered microscope. Your microscope reveals that each spore is 10 microns (micrometers) in length.

How many spores will be found in the diameter?
