North High School will have its first graduating class in the year 2001. To celebrate, it has designed watches with a gold leaf sector between the 12 and the 1 as shown.
Next year's graduating class will have gold between the 12 and the 2 as shown. Each of the first twelve graduating classes will have a similar design. This way, when graduates meet other alumni many years from now, they will instantly be able to determine which year they graduated.
As student body president, Susan is concerned with the cost of the watches and needs to tell the jeweler the amount of gold each watch will require. If the radius of the face of the watch is 2 cm, help Susan out by making a table with the areas of gold leaf for each of the first 12 graduating classes.
If telephone poles (18 feet tall) suspend a telephone wire off the ground along the equator, how much longer than the equator would the wire be? (Ignore the sag between poles.)
