Step 1: Identify the known or given information.


Step 2: Set up a formula for the sector area

            NOTE:  A ratio will need to be constructed. Recall that a circle is composed of 360 degrees. Therefore, the following ratio can be made,

             \frac{\theta}{360} = \frac{\text{sector area} (A_C)}{\text{Total area} (A_T)}

                  where, \theta=Central\ angle

Step 3: Plug the sector’s central angle measurement into the formula. 


Step 4: Plug the given area measurement into the formula.

            EXAMPLE:   \frac{26}{360} = \frac{\text{sector area} (A_C)}{\text{46} (A_T)}

Step 5: Solve the area.


EXAMPLE: \frac{\theta}{360}=\frac{Sector\ area\ \left(A_C\right)}{Total\ area\ \left(A_T\right)}

                     \frac{26}{360} = \frac{\text{sector area} (A_C)}{\text{46} (A_T)}

             \frac{26}{360} * 46 = \text{Sector area} (A_C)

            sector area = 3.22
