Find the area of the shaded region. Round your answer to one decimal place, if necessary figure is not drawn the scale

Step-by-step explanation:
area of equilateral ∆ =
[tex]( \sqrt{3} \div 4) {a}^{2} [/tex]
here a = 3
area of ∆ = 3.9 in^2
area of circle
[tex]\pi {r}^{2} [/tex]
= 19.63 in^2
area of shared region = 19.63-3.9= 15.73 in^2
