Answer:
A ≈ 55.6 cm²
Step-by-step explanation:
The area (A) of the shaded region is calculated as
A = area of circle × fraction of circle
central angle of shaded region = 360° - 230° = 130° , then
A = πr² × [tex]\frac{130}{360}[/tex]
= π × 7² × [tex]\frac{13}{36}[/tex]
= 3.14 × 49 × [tex]\frac{13}{36}[/tex]
≈ 55.6 cm° ( to the nearest tenth )
