well, to find x recall the area of a sector, so you want
(1/2)(3.5^2)x = 27.5
x is in radians, so you will have to convert to degrees.
In a diagram O is the centre of the circle,if angle<POQ is x and diameter is 7cm while the area of the shaded portion is 27.5cm^2.find correct to the nearest degree the value of x.(take pie as 22/7)
