Use the diagram to answer the questions. what is the area of the circle in terms of pi? π units² what is the measure of the central angle of the shaded sector? ° what is the area of the shaded sector rounded to the nearest whole number? units²

121

143

151

Step-by-step explanation:

The radius of the circle is 11, so the area is

The central angles of the shaded and non-shaded regions sum up to 360 degrees, so the central angle of the shaded region is

The area of the shaded region is in proportion with the area of the whole circle: if the whole area is given by a sector of 360°, the area of a 143° sector will be given by

Since we know that the whole area is , we can solve for the area of the 143° sector:
