The equation of a circle tangent to the x-axis with a center at (3, 5) is derived using the formula (x - h)^2 + (y - k)^2 = r^2. Here, h is 3, k is 5, and the radius r is equal to 5, as the distance from the center to the x-axis is 5. Substituting these values, the equation simplifies to (x - 3)^2 + (y - 5)^2 = 25. The calculations confirm the correctness of the equation. This demonstrates a clear understanding of the geometric properties of circles.

Find the equation of the circle tangent to the x-axis and with center (3, 5).

(x - h)^2 + (y - k)^2 = r^2

h = 3, k = 5

r = 5

(x - 3)^2 + (y - 5)^2 = 5^2

(x - 3)^2 + (y - 5)^2 = 25

Yes?

Yes, all correct. (Yes)
 
Always good to be right.
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
