    Since AO is equivalent to AB it is a isosocles triangle.

    SO from that we can calculate angle o and angle b are 40 degrees

    \[\frac{ x }{ 360 } \times \pi r^2\]

    x would be 40, as we found angle O was 40. this means the shaded area is 40 degrees of the whole 360 degrees of the circle.

    so \[\frac{ 40 }{ 360 } \times \pi 6^2\]

    then \[\frac{ 1 }{ 9 } \times 36 \]

    so then once you multiply 1/9 and 36, you get 4, which then would equal 4 pi
