===
Today (August 23) is Buttered Corn Day!

Suppose you have a perfectly cylindrical ear of corn (don't worry, it's buttered). It has a height of 17.78 cm and a diameter of 5.08 cm.
Furthermore, suppose each kernel is a perfect circle with a radius of 3.6 mm.
About how many kernels are on the ear of corn?
