If an isosceles triangle `A B C` in which `A B=A C=6c m` is inscribed in a circle of radius `9c m ,` find the area of the triangle.

Explanation

To find the area of the isosceles triangle \( ABC \) inscribed in a circle of radius \( 9 \, \text{cm} \) with \( AB = AC = 6 \, \text{cm} \), we can follow these steps:

### Step 1: Draw the Diagram
Draw a circle with radius \( 9 \, \text{cm} \) and inscribe triangle \( ABC \) such that \( AB = AC = 6 \, \text{cm} \). Let \( O \) be the center of the circle.

### Step 2: Identify Key Points
Label the points:
- \( A \) is one vertex of the triangle.
