Question

in a figure o is the center of circle the area of sector APOB is 5/18 of the area of circle find x​

Answer 1

Answer:

Ans. Let Angle of Sector  = θθ

Radius of Circle = r 

Area of Circle = πr2πr2

Area of Sector = π×r2×θ360π×r2×θ360       

According to Question,

=>π×r2×θ360=518πr2=>π×r2×θ360=518πr2

=>θ=518×360=100
