a simple dart board has 3 areas...the main board has a radius of 9 in, there is a circle with a radius of 6 in, and the bullseye has a radius of 2 in. what is the probability of a random dart landing inside the bullseye. I'm a little confused.

a simple dart board has 3 areas...the main board has a radius of 9 in, there is a circle with a radius of 6 in, and the bullseye has a radius of 2 in.  what is the probability of a random dart landing inside the bullseye.  I'm a little confused.

anonymous · Answer

area of the bulls eye divided by total area

anonymous · Answer

$$\frac{4\pi}{81\pi}=\frac{4}{81}$$

anonymous · Answer

as the area of a circle with radius $r$ is $\pi r^2$

anonymous · Answer

ok  so the probability would be 4/81 as well

anonymous · Answer

yes
