Question

The radius of a circle is 14 cm. What is the area of a segment whose arc is of measure?
120 degree

Answer 1

Hi Mate!!!

Itz area can be calculated by two different ways.

Ist way :-

Itz area = 1/2 { 120 - Sin(120) } r²

Sin ( 120 ) = √ 3 / 2 and r = 14

=>. itz area = 1/ 2 { 120 -√3/2 } 196

=>. itz area = 11675.131cm²

2nd way :-

Required area ={ 120 / 2 } × 196 - 196 ( √3 ) / 4

Required area = 11675.131cm²

Have a nice time
