A rectangle is inscribed in a circle of radius 8. Let P=(x,y) be the point in quadrant 1 that is a vertex of the rectangle and is on the circle.

Let's break down the problem systematically.

### Given:
- A rectangle is inscribed in a circle of radius 8.
- One vertex of the rectangle is located at point \( P = (x, y) \) in quadrant 1 on the circle.

### Analysis:

1. **Circle Equation**:
   The equation of a circle with radius 8 and centered at the origin is:
   \[
   x^2 + y^2 = r^2
   \]
   where \( r = 8 \), so:
   \[
   x^2 + y^2 = 64.
   \]

2. **Rectangle Symmetry**:
   Since the rectangle is inscribed in the circle, the other three vertices of the rectangle will be symmetric to \( P = (x, y) \):
   - \( (-x, y) \) in quadrant 2,
   - \( (-x, -y) \) in quadrant 3,
   - \( (x, -y) \) in quadrant 4.

3. **Rectangle Dimensions**:
   The length and width of the rectangle can be determined based on the coordinates of the vertices:
   - Length (horizontal distance): \( 2x \),
   - Width (vertical distance): \( 2y \).

4. **Area of the Rectangle**:
   The area of the rectangle is the product of its length and width:
   \[
   \text{Area} = 2x \cdot 2y = 4xy.
   \]

### Summary:
- The point \( P = (x, y) \) satisfies \( x^2 + y^2 = 64 \), since it lies on the circle of radius 8.
- The area of the rectangle is \( 4xy \).
