If a circle has radius 3, its area is which of the following?

Explanation:
Area of a circle is found using the formula π times the radius squared. With a radius of 3, the radius squared is 9, so the area is 9π. The other options would require different radii (for example, an area of 3π would come from radius √3, 27π from radius √27, and 18π from radius √18), but for a radius of 3 the area must be 9π.
