Question

IN the fig ab=36cm.M is the mid point of ab. Three semi circles are drawn on ab am and bm as diameter. Find the shaded region.

Answer 1

Please provide figure if you want answer

Answer 2

Answer:

area of big semi circle =1/2 (22/7) R^2

AREA OF 2 SMALL SEMI CIRCLE IS = 22/7 r^2

R =36/2 =18

r =18/2 =9

req area =1/2 (22/7) R^2    -   22/7 r^2

              =(22/7)[1/2][18][18] -[22/7][9][9]

              =[22/7]{162 -81}

             =22/7 {81}
