Answer:
1065.09 square meters
Explanation:
The inner circle has a diameter of 21.4 cm
Its radius is half that = 21.4/2 = 10.7 m
Area of the inner circle = π (10.7)² = 114.49π m²
The outer circle has a radius
= radius of inner circle + 10.6
= 10.7 + 10.6
= 21.3 m
Therefore the area of the outer circle
= π(21.3)² = 453.6π m²
Area of shaded region
= Area of outer circle - Area of inner circle
= 453.6π - 114.49π
= 339.2 π
Taking π = 3.14
Area of shaded region
= 339.2 x 3.14
= 1,065.088 m²
= 1065.09 m² (rounded to nearest hundredth)
