If the circle with centre
- Solution
Given the area of the circle is
9π .Then, the radius of the circle will be
3 .Therefore,
AD=6 (diameter of the circle.)AD is the height of an equilateral triangle.12×a ×6 = 3√4×a2 a =123√ The area of the equilateral triangle
=12 ×123√×6 =363√=(12×3)3√=(12×(3√)2)3√=123√
