Answer:
50.27 cm²
Step-by-step explanation:
Subtract the area of the smaller circle from the area of the larger circle
The area of a circle = πr² ( r is the radius )
area = π × 5² - π × 3² = 25π - 9π = 16π ≈ 50.27 cm² ( nearest hundredth )
Answer:
Area of the colored section = 50.29 cm²
Step-by-step explanation: .
The picture below illustrate the how the smaller circle sit inside the bigger circle. The colored region is the what we are after . The area of the colored region is the subtraction of the area of the smaller circle from the bigger circle.
Area of circle = πr²
Area of the inside circle = π ×3²
Area of the inside circle = 9π
Area of the outer circle = πr²
Area of the outer circle = π × 5²
Area of the outer circle = 25π
Area of the colored section = 25π - 9π
Area of the colored section = 16 × 22/7
Area of the colored section = 352/7
Area of the colored section = 50.28571429
Area of the colored section = 50.29 cm²
