Heya mate,
I am not dling thw whole solutions but i can use the formula of area of segment of a circle.
i.e. Theta/ 360*pi r^2- half r^2 sin theta....
Where
theta is the central angle,
Sin theta's value is to be filled by the table in trigonometry...
Here, sin 120° will be equal to
sin(180°-60°) =sin 60° ie root 3/2
Hope it helped u...
I didn't answer full becoz i too have boards and have to prepare..
Sorry for the inconvenience..
Althe best for maths exam :)
