**bobpursley**, Friday, July 22, 2011 at 5:09pmNo, you have to do this on the basis of area (which is proportional to radius^2)

pr(bullseye)=(2/11)^2

**Jen**, Friday, July 22, 2011 at 5:19pmso it would be 0.0330??

**bobpursley**, Friday, July 22, 2011 at 6:45pmI would have rounded to 0.00331

**Ms. Sue**, Friday, July 22, 2011 at 6:50pmRounded to the nearest thousandth -- wouldn't that be 0.033?

**Jen**, Friday, July 22, 2011 at 7:08pmOh i forgot to ask....would i use A=Pir^2?

**Damon**, Friday, July 22, 2011 at 7:30pmYou can use pi r^2 but since you are just taking ratios the pi will cancel.

4 pi/121 pi = 4/121
