A heinous prank was perpetrated at Rudrum University. It was found that four students had painted a large circle on the floor of the cafeteria. Professor Templeton was talking to the Maintenance man who was hired to replace the gratified floor tiles at the expense of the four students.
“I’m a fair man. I only will charge them for my time and materials”, the Handy-man said.
“How many tiles will tiles need to be replaced?”, asked the Prof.
“Haven’t counted ‘em, yet. All I did so far was determine that the circle is 27 feet in radius”
“Hmm. I notice that the circle doesn’t lie on the edge of any tile and it never touches the intersection of any four tiles either.”
“Um, O.K. You teacher types notice weird things, don’t ya?”
“I guess we find some things interesting, yes. So what are you going to charge for this job?”
“The tiles are 9 inches by 9 inches and they only come in boxes of 10 at $11.20 per box. My labor rate is $30.00 per hour, but I break it down into 15 minute increments and I figure I can replace about four tiles in 15 minutes time.”
