Sum of areas of all the three circles is 464
Step-by-step explanation:
Given: Three concentric circles with center D.
Let C(D,r) be the smallest circle with radius r=CD=8 inches. r'=BD is radius of the middle circle C(D,r') and AB=r"=be the radius of the largest circle C(D,r").
Solution: Also, CB = BA=4 inches.
BD = BC + CD = 8+4 = 12 inches
AD = AB + BD =4 + 12= 16 inches
Now, we will calculate the areas of different circle separately.
Area of circle C(D,r) = = 8*8* = 64 (1)
Area of circle C(D,r') = = 12*12* = 144 (2)
Area of circle C(D,r'') = = 16*16* = 256 (3)
Total area of all the three circles is adding equation (1), (2),(3).
(64+144+256) =464
