Answer 1

so first you need to calculi area of this circle
and because the blue sector of the circle is formed by radius what has formed an angle of 120 degree so and because 120 is a 1/3 rd part of 360 degree what has a circle so for this result that you need just divide the total area of this circle by 3 and so will get area of the blue sector

hopw so much that this will help you calculi it and understand it sure right easy

good luck
