Answer:
Step-by-step explanation:
The area of the shaded portion, we have to calculate.
Now, join C and O to form two right triangles Δ AOC and Δ BOC.
Now, from Δ AOC,
⇒ x = 6√3
So, area of Δ AOC =
Due to symmetry area of Δ BOC will also be 18√3.
Now, area of quadrilateral OACB is 2 × 18√3 = 36√3
Now, area covered by the arc AB about center O will be
Therefore, the area of the shaded portion is (Answer)
Answer:
36\sqrt{3} -12\pi
