Question

find the probability of a point chosen at random being in the shaded area of the diagram at the right

Answer 1

Answer: 1/9

Explanation:

The area of the shaded region is
`(4/2)^2 \pi =4\pi`

The area of the entire circle is
`(6)^2 \pi=36\pi`

So, the probability is
`(4\pi)/(36\pi)=1/9`
