Answer:
First find area of small circle
radius = 5 - 3 = 2cm
Area of circle = πr×r = 22/7 × 2 × 2= 88/7 cm^
Then find area of big circle
Radius is 5cm
Area of circle = 22/7 × 5×5 = 550/7cm^
Area of shaded region = 550/7 - 88/7 = 462/7 = 66cm^
Answer is 66 cm^
Answer:
Inner circle area=
2*22/7*2*2
=178/7
Outer circle area
2*22/7*3*3
=396/7
Area of path = outer area - inner area
396/7- 178/7
=218 cm²
