Question

area of sector of a circle of radius 14 cm is 154 cm square .find the corresponding arc of the sector​

Answer 1

Answer:

let radius be r and the angle made at centre be x

 

=> area of sector = 154 cm2  

=> (x pi r2) / 360 = 154 cm2

=>  x = (154 *360) /  (pi* 142)

=> x = 90.04 degrees

 

Now length of the arc = (x * 2 pi r) / 360

                          = (90.04 * 2* pi*14)/360

                           = 22 cm (approx ) answer
