Question

quotion is the picture ​

Answer 1

Step-by-step explanation:

to get area of shaded region we need subtract area of sector OPAQ from total area of figure. total area is sum of triangle and semicircle

consider the triangle. since it's all sides are equal it's an equlateral triangle.

So, area = side² × √3/4

= 100√3/4

= 25√3

Area of semicircle with diameter PQ

= πr²/2

= 25π/2

Area of sector OPAQ

= 60/360 × π × 10²

= 50π/3

Area of shaded region = 25√3 + 25π/2 - 50π/3

=25( √3 + π/2 - 2π/3)

= 25( √3 - π/6).
