Answer:

10 units

Step-by-step explanation:

Because the center of the circle is at (9 , 9) and passes through (4 , 9), the radius must be 5.

Radius - The length from the center of a circle to its edge

Diameter - The length from one edge of a circle to the opposite edge

The diameter is double the length of the radius, meaning D = 2(5).

2 × 5 = 10

So, the diameter of the circle is 10 units.
