YaYiee ThanksS!! and I got The AnswEr for the FIrst Question!!
its So damn EAsYY !:O Aishu Didd ITt! :D See its Lyk Diss
SOmeWAT:
The sum of the angles of a triangle is 180 degree.
So lets name them <x <y and <z....Then X+y+z=180!!
Then...Area of the entire thingy = Area of three sectors ryte?
So, RAdiues = 7cm!! (the lenth of their ropes was 7 cm!)
in that case, area of each sector would be: x/360 . pi r2 +
y/360 . pi r2 + z/360 . pi r2!! (r2 means radius square!! u noe
the formula for area of a secto ryte?)
So noww, pi r2 and 360 r common kk?
Then, taking them common it will be: X+y+z/360 . Pi r2!!
We knw that X+y+Z=180!!
So 180/360 . pi r2!! :D ow u calculate!! :D and find d answerr!!
