First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle. area of the larger sector:(230/360)π*11.1²≈247.17 area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130 (11.1*11.1*sin130)/2≈47.19 the total area is 247.17+47.19≈294.4 Please use your calculator to double check my numbers.
