Question

Find the area of shaded region.
In which side=12cm and radius=6cm​

Answer 1

Step-by-step explanation:

Required area : area of triangle + area of major sector

area of triangle : root 3 by 4 a^2

=36 root 3 cm^2

area of major sector ; theta by 360 pie r^2 = 94.2 cm^2

Required area : ( 94.2+36 root 3 ) cm^2

Answer 2

Step-by-step explanation:

area of eq triangle = (√3/4)a^2

= 36 × 1.73

area of circle= πr^2

= 36π

for π/3 =( 36π × π/3) / 2π

= 6π

area of shaded reasons= 36√3 + ( 36π – 6π )

= 36√3 + 30π cm^2
