Mathematics Question and Solution
Shaded Area is;
Area sector with radius 1 unit and angle 2atan(½)° - Area triangle with two lengths 1 unit each and angle 2atan(½)°, the angle they form + Area sector with radius ½ units and angle 2atan(2)° - Area triangle with two lengths ½ units each and angle 2atan(2)°, the angle they form.
= (2atan(½)π/360)-(½sin(2atan(½)))+(2atan(2)*0.25π/360)-(½*0.25sin(2atan(½)))
= 0.063647609+0.17678717945
= 0.24043478845 square units.
