1) There are a bunch of friends in advanced math class learning about PI.  This was on their paper:                                                                                                                                

Pi-p

p=3.14159...

R=5

D=?                                                               What does C equal?

C=?                                                               Bonus: what does A equal

pR²=A

pD=C

Rx2=D

2) Some friends in math class were given an extra credit problem.  It looked like this:                                   

                                      C             A²+B²=C²      What is C?

                     A                              A=2               Bonus: what is the area?    

                                   B                 B=4              (Hint: base x height=area)

3) Some friends tried to figure out this problem: how many 3’s are from 1 to 500?
