Question

Area of sector of central angle 200 degree of a circle is 770cm. Find the length of the corresponding arc of this sector

Answer 1

Solution :-

Given that the central angle of the sector is 200 degree. 

or θ = 200

And, area of the sector = 770 cm²

Area of the sector = πr²*θ°/360°

⇒ 770 = 22/7*r²*200/360°

⇒ r² = 1940400/4400

⇒ r² = 441

⇒ r = √441

⇒ r = 21 cm

Now, length of the corresponding arc of this sector

= 200*21*π/180°

= 200*21*22/7*180

= 9240/126

= 220/3 cm

= 73 1/3 cm
