Answer:
Option (B)
Explanation:
Area of sector of a circle =

where r = radius of the circle
θ is the central angle subtended by the arc TS.
Area of the given sector =

=

= 192π
= 603.19 unit²
Area of the triangle (not shaded) =

=

= 167.22 unit²
Area of the shaded area = Area of the sector - Area of triangle
= 603.19 - 167.22
= 435.96 unit²
Therefore, the area of the shaded region = 435.96 unit²
The nearest value of the area has been given in Option (B).
So Option B will be the answer.
