Area of a Sector of a Circle
O is the cent...
Question
O is the centre of circle . If the area of sector OAPBA is 5/36 times the area of the circles then find the value of theta .
Open in App
Solution
Let x= central angle and r= radius of the circle.
Area of sector = 5/36th of area of circle
Pi*r²*x/360 = 5/36 * pi*r²
X/360 = 5/36
X = 50 degrees
