One of Jimmy's _ bubbles turned out to look a little like the one at ' ` _ the left. / o \ ' ` | \ Suppose Jimmy's "double bubble" consists of two \ | spheres whose centers are 14 cm apart. If the two ` _ ' \ spheres intersect in a circle whose radius is 12 cm, ` o / and the radius of one sphere is 13 cm, what is the ` _ ' radius of the other sphere? o Correct solutions to the problem were submitted by: Susan Quan, Grade 7 Masterman Philadelphia Christina Molinari, Grade 9 Masterman Phila.
