Explanation:
Area of the large circle =πR²
=3.14×(3)²=3.14×9=28.26cm²
Area of one small circle= πr²= 3.14×1= 3.14cm²
Area of two small circles = 2×3.14 cm²= 6.28cm²
Area of the shaded region= (28.26-6.28)cm²
= 21.98 cm²
Answer:
7pi or ≈21.98 cm²
The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi
the area of the 2 smaller circles is pi1^2*2 so 2pi
9pi-2pi=
7pi cm² =
7pi≈21.98 cm² (with pi as 3.14)
