13. A circle exists entirely in the first quadrant

such that it has a tangent on the y-axis at
y = 6. If the circle also have a tangent on
the x-axis, what is the area of the circle?

Final answer:

To find the area of the circle in the first quadrant with tangents on the y-axis and the x-axis, we can use the formula A = πr², where r is the radius of the circle. In this case, the area of the circle is 36π square units.


Step-by-step explanation:

To find the area of the circle, we need to determine its radius. Since the circle has a tangent on the y-axis at y = 6, we know that the distance from the center of the circle to the y-axis is 6 units. Let's call this distance r.

Since the circle also has a tangent on the x-axis, the distance from the center of the circle to the x-axis is also r units.

The area of a circle is given by the formula A = πr². So, the area of this circle would be A = π(6)² = 36π square units.
