You can't calculate the area (square feet) of a radius. A radius is a line segment that connects the center of a circle to a point on the circle's edge.

To calculate the area of a circle, you need the radius. Here's the formula:

* Area = π * r²

Where:

* π (pi) is approximately 3.14159

* r is the radius

So, for a 16 foot radius:

* Area = 3.14159 * (16 feet)²

* Area = 3.14159 * 256 square feet

* Area ≈ 804.25 square feet
