Answer:
12(10π + 3√3)m²
Explanation:
Given:
Radius = 12 m
Area of a circle = π r²
A = π* (12m)²
A = π * 144 m²
A = 144π m²
360°/60° = 6
144πm² * 5/6 = 120π m² Area of the remaining circle.
Area of the equilateral triangle = (√3/4) a²
* radius of the circle is the side length of the triangle.
A = (√3/4) * (12m)²
A = 36√3m²
Area of the shaded region = (120π + 36√3)m²
= 12(10π + 3√3)m²
