Question

find the area of the shaded region

Answer 1

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 2

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
