What is the probability of a random dart landing inside the bullseye?

9. satellite73

ok. now we can do it. "random" means you don't aim, so it can be anywhere. take the ratio of the areas.

10. satellite73

area of bulls eye is $9\pi$ area of dartboard is $100\pi$ ratio is $\frac{9}{100}=.09$ (the pi cancels)
