Question 381347
A simple dartboard has three areas… the main board has a radius of 10 inches, there is a circle with a radius of 7 inches, and the bullseye has a radius of 3 inches. What is the probability of a random dart landing inside the bullseye? 

------
Prob(bullseye) = (area of bullseye)/(area of board)
= (pi*7^2)/(pi*10^2) = 49/100
