Answer 1

Answer:

option ( b ) is the correct answer

Step-by-step explanation:

find the area of the larger circle:-

area = pi r^2= pi(2)^2

= 4pi cm^2

find the radius of the smaller circle:-

radius of the larger circle = diameter of the smaller circle

radius = 2÷2=1 cm

find the area of 1 small circle:-

area = pi r^2 =pi (1)^2 =pi cm^2

find the area of 2 such small circle:-

area of 1 circle = pi cm^2

area of 2 circle =2 pi cm^2

find the area of the larger circle that is not covered by 2 smaller circles:-

area is not covered =4 pi -2 pi = 2 pi cm^2

find the shaded region:-

shaded region = 2 pi ÷ 2

= pi cm^2
