Answer 2

Answer:

16π/3 -  4√3   cm²

Step-by-step explanation:

height of triangle =  AB×sin 60  = 4×√3/2 = 2 √3 cm

Area triangle ABC = 1/2 × 4 ×2√3 = 4 √3  cm²

Area of circle = π r²  = π  (4/√3)² = 16π /3  cm²      as radius of circumference of circle = AB / √3

Area of the Shaded area = 16π/3 -  4√3   cm²
