A simple dartboard has three areas the main board has a radius of 9 inches there is a circle with a radius of 5 inches ans the bullseye has a radius of 3 inches What is the proability of a random dart landing inside the bullseye Round to the nearest 1000th

Answer 1

I am assuming that you you disregarding any skill factor involved and you are certain that the dart will land randomly inside the circle.

Area of whole circle = π(81) = 81π
area of inner circle = π(9) or 9π

prob of landing in inside circle = 9π/(81π) = 1/9 or .11
