What is the area of a circle with radius 3?

Explanation:
Area of a circle is π times the radius squared. With radius 3, the area is π × 3^2 = 9π square units. The other numbers would come from different radii (for example, a radius of √6 gives 6π, √3 gives 3π, and 2√3 gives 12π), so for a radius of 3 the area is 9π.
