Answer:
Option C
The Area Of Shaded Region is 50.2 cm²
Explanation:
For A given Circle,
For Small (Non-Shaded) Circle:
Diameter (d) = 6 cm
Radius = d ÷ 2 = 6/2 = 3 cm
For Area of Small (Non-Shaded) Circle
Formula:
A = πr²
A = 3.14 × (3)² cm
A = 3.14 × 9 cm
A = 28.26 cm²
For Area of Big (Shaded) Circle:
Diameter (d) = 10 cm
Radius = d ÷ 2 = 10/2 = 5 cm
For Area of Small (Non-Shaded) Circle
Formula:
A = πr²
A = 3.14 × (5)² cm
A = 3.14 × 25 cm
A = 78.5 cm²
For The Area Of Shaded Region
Area of Big Circle - Area of Small Circle
78.5 cm² - 28.26 cm² = 50.24 cm²
Thus, The Area Of Shaded Region is
50.2 cm²
