Answer:
QR is the tangent to circle
PR=12cm PQ=6cm
in triangle PQR
by pythagoras theorem
QR= 10.38 or 6root 3
thus it is 30 60 90 triangle
angle p= 60
PQ=PT
Area of sector
60/360×3.14×6×6= 18.85
Area of triangle PQR
1/2×10.38×6=31.14
Area of triangle _area of sector
31.14_ 18.85
= 12.29
area of shaded region = 12.29
