Question

in the given figure ABC is an equilateral triangle inscribed in a circle of radius 4 cm find the area of the shaded region ​

Answer 1

Answer:

9.83 cm^2

Step-by-step explanation:

Given = radius of circle = 4 cm

To find : Area of ∆

Proof = Area of eq ∆ in circle = 1/2 × 3√3 r^2

Area = 1/2 ×3√3×4×4

Area = 12√3 cm ^2

Hence, area is 12√3 cm ^2

Area of shaded region = area of circle - area of triangle.

area of shaded region = 1/3 ×[50-28-12√3]

= 1/3 [ 50-28-20.78]

= 9.83 cm^2

Hence, area of shaded region is 9.83 cm^2
