Happy Friday the 13th. If you know what is good for you, stay in your cabin this weekend, kiddies.
Here is some light reading to keep you safe and occupied while you cower behind closed doors. If you are a fast reader, perhaps a riddle will help you resist the urge to go wandering through the woods. Two of our panelists this week helped me cook this up. Last week, we had a party in the form of Bungie Day. Do you know what was missing? Michael Williams and David Johnson do...
Time to make paper party hats! You have a paper circle of radius r. You cut an angle a wedge out of it, and pull the circle together to make your hat. If you set your resulting hat on the table, what is the angle between the side of the cone and the table? (In other words what is the steepness of the cone?) Find a reduced formula that relates the radius r and angle a to the resulting steepness.
Figure that out, and you win some loot.
