Hi, I can help get you started. First of all the area of a circle is $\pi \; r^2$ where $r$ is its radius. Your circle has an area of 154 square centimeters so what is its radius? Since the area of the third sector is 3 times the sum of the areas of the first two sectors if you divide the circle into 4 equal sized sectors then the third sector is made up of 3 of these four sectors and the first two sectors make up the fourth of the 4 sectors.
