Answer:
21.8 square units
Step-by-step explanation:
The shaded area is made up of two sectors. Each sector has a central angle of 50 degrees.
Add the two 50 deg angles, to get 100 deg.
The shaded area is the are of a sector with 100-deg central angle.
[tex] A_{sector} = \dfrac{n}{360^\circ}\pi r^2 [/tex]
where n = measure of central angle of sector.
[tex] A_{sector} = \dfrac{100^\circ}{360^\circ}(\pi)(5^2) [/tex]
[tex] A_{sector} = 21.8~square~units [/tex]
