Solution

Problem 5 :

Naomi makes silver jewelry. For one style of earnings she cuts wedges from a silver disk, as shown in the center of the disk. If the weight of each uncut disk is a uniformly distributed 2.5 grams, how many grams does each wedge weigh?

Solution

Problem 6 :

The flag shown is made of overlapping equilateral triangles ADF and BCE. Because ribbon is to be sewn around the entire outer edge, it is necessary to know the perimeter of the flag. If CD, DE, and EF each have length 10 inches, what is the length, in inches, of the perimeter shown in bold?
