Answer :

Each angle of triangle = θ = 60°

Area of triangle not included in circles = Area of triangle – Area of all sectors

Area of all 3 sectors area equal as all the three circles are having same radius which is equal to the half of the side of the equilateral triangle.

Let the side of equilateral triangle be = a cm

⇒ a = 7×2

⇒ a = 14 cm

So radius of the circles = 7 cm

∴ Area of all 3 sectors = 77 cm^{2}→ eqn1

Area of triangle not included = (49×1.73) - 77

⇒ Area of triangle not included = 84.77 – 77

∴ Area of triangle not included = 7.77 cm^{2}

Area of triangle not included in circles is 7.77 cm^{2}.
