Question

the figure is formed by two big and two small semicircles find the shaded area take pie as 3.14
please help me friends I will mark you as brain list ​

Answer 1

Step-by-step explanation:

given=diameter of semi circle= 10+6

=16

diameter of small circle=6

find radius

big semi circle = 8

small semi circle = 3

solve

area of 2 big semi circle= 2πr²

2*22/7*8*8

3016/7 ..............(1)

area of small semi circle= 2πr²

2*22/7*3*3

396/7 .............(2)

shaded area

eq (1) - (2)

3016/7-396/7

2620/7

ans= 374.28
