Question

Find the area of the shaded segments and round to the nearest 10th.

**Question 11**

A diagram of a circle is shown with a shaded sector. The central angle of the shaded sector measures 120°. The radius of the circle is labeled as 4 units. 

**Question 12**

A diagram of a circle is shown with a shaded sector. The central angle of the shaded sector measures 60°. The radius of the circle is labeled as 1 unit. 

**Explanation of Diagrams**

1. **Diagram for Question 11**: The diagram features a circle with a shaded sector. The central angle of the shaded sector, represented by a curved line, measures 120°. The radius of the circle, which is the distance from the center of the circle to any point on the circle, is given as 4 units.

2. **Diagram for Question 12**: The diagram features a circle with a shaded sector. The central angle of the shaded sector is 60°, marked by two radii extending from the center to the circumference, forming the angle. The radius of the circle is 1 unit.
