Step by step:
AC = 8 cm ( radius of big circle)
AB = 3 cm
Thus, BC = 8 - 3 = 5 cm ( radius of small circle)
We know, Area of circle = π r × r
Therefore, Area of small circle = 5 cm × 5 cm × 22/7
= 25 × 22/7
= 550/7 sq. cm
Area of big circle = 8 × 8 × 22/7
= 64 × 22/7
= 1408/7 sq. cm
Therefore, Area of shaded part = area of big circle - area of small circle.
so, 1408 - 550/7
= 858/7
Answer:
= 121.57 sq. cm (approx.)
