Answer:
Step-by-step explanation:
diameter = AOB
∠ACB = ∠ADB = 90
Aspect ratio of ABC = AR of ABD = 1/2 BC x AC
Aspect ratio of ABC = AR of ABD= 60 cm2
by using pythogaros theorem
AB² = AC² + BC²
AB²= 15² + 8²
AB = 17cm
radius = 17/2
Ar of C= 22/7 x 17/2 x 17/2
= 3179/ 14 cm2
AR of shaded region = Ar of C - Ar of ABC - Ar of ABD
= 3179/14 - 60 - 60
= 1499/14 cm2
