Answer:
E
Explanation:
First we need to find the radius of the circle using the shaded sector and the formula for its area:
120/360(πr²) = 27π
Cancelling the π’s and rearranging gives us r = 9
To find the length of the white sector’s arc, we first find the reflex angle at the centre by doing 360 - 120 = 240 degrees
So the length of arc AXM will be 240/360(2π(9)) = 12π
