329.7 cm²
Step-by-step explanation:
Step 1:
To find the area of the shaded region, we will subtract the smaller area from the larger area.
Step 2:
Area of Circle = π [tex]*[/tex] r²
Where, r= radius of circle
π = 3.14
Here Larger circle area (A) = π [tex]*[/tex] 11 [tex]*[/tex] 11 ( r = 11 cm)
= 379.94 cm²
Smaller circle area (a) = π [tex]*[/tex] 4 [tex]*[/tex] 4 ( r = 4 cm)
= 50.24 cm²
Step 3:
Shaded Area = A - a
= 379.94 - 50.24
= 329.7 cm²
