A simple dartboard has three areas… the main board has a radius of 11 inches, there is a circle with a radius of 5 inches, and the bullseye has a radius of 3 inches. What is the probability of a random dart landing inside the bullseye?
Round to the nearest thousandth. (Hint: Use A = π r²)
----
Area of bullseye = (pi)*3^2
---
Area of board = (pi)*11^2
---
P(land in bullseye) = [(pi)*9]/[(pi)*121] = 9/121 = 0.074
