Answer:

The standard equation for a circle with a center at the point (h, k) and a radius of r is:

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

In this case, you are given the center at (3, 6) and a point on the circle, (6, 10). To find the radius (r), you can use the distance formula between the center (h, k) and the given point (6, 10):

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Distance = √((6 - 3)^2 + (10 - 6)^2)

Distance = √(3^2 + 4^2)

Distance = √(9 + 16)

Distance = √25

Distance = 5

So, the radius (r) is 5.

Now, plug in the values into the standard equation:

\[(x - 3)^2 + (y - 6)^2 = 5^2\]

Simplify:

\[(x - 3)^2 + (y - 6)^2 = 25\]

This is the standard equation for the circle with a center at (3, 6) and passing through (6, 10).
