Answer:
area of shaded region = 16.768 cm²
Step-by-step explanation:
OA = 7cm
angle POA = 60°
angle BAO = 90° ( tangent is perpendicular to radius)
therefore
tan60 = BA/ OA
√3 = BA /7
BA = 7√3
NOW
area of shaded region = Area of triangle - area of sector
=( 1/2 × 7 × 7√3) - 60/360 × pi × 7 × 7
= 49√3 / 2 - 1/6 × 22/7 ×7 ×7
= 42.435 - 25.667
= 16.768
