Question

Can you answer this

Answer 1

Area of shaded region = Area (sector OAPB) - Area (Triangle OAB)
Area of sector =
`(C)/(360) \pi r^(2)` = 24.504 sq.cm
Area of triangle =
`(ab sin(C))/(2)` = 17.61 sq.cm

Area of shaded region = 24.504 - 17.61 = 6.894 ≈ 6.89 sq.cm

//r = radius; C = angle between radii / Sides; a,b = sides of the triangle
