Big Nate: First Class by Lincoln Peirce for January 16, 2015
Dad, what's the difference between "Radius, Diameter, and Circumference"? Well, lets see ... Radius is the distance across... No, wait a minute... say you have a circle and you... or would it be a sphere? OK, let's say you're in the middle of a circle the diameter is the length... No, Hold it. I'll just go stand in the street... maybe some passing motorist can help me.
