Question

find the area of shaded region where AGB,AEC,CFD,DGB are semicircles on diameter AB,AC,CD,DB respectively and AC:CD:DB= 3:2:2 ​ ​

Answer 1

Answer:

Step-by-step explanation:

Area (APD) = pi/2 * 7^2

                   = 77

Area (AQB) = pi/2 * 1.75^2

                   = 4.81

Area ( BRC) = pi/2 * 49/4

                   = 77/4 = 19.25

Area (CSD) = pi/2 * 1.75^2

                    = 4.81

Thus Area of shaded Region = 77+ 2* 4.81 + 19.25

                                               = 105.87 unit sqr
