# Circle Conundrum

**Geometry**Level 1

If the area of the circle can be expressed as \(A \pi \text{ cm}^2 \), find the value of \(A\).

A rectangle is drawn in a circle so that one vertex lies on the center point of the circle, and the opposite corner lies on the circumference. The height of the rectangle is \(8\text{ cm}\), and its diagonal is \(10\text{ cm}\).
