Plz help with equation of the circle will award fastest CORRECT answer with brainliest

Step-by-step explanation:

The equation for a circle is given by:

Where (h,k) is the center and r is the radius.

The center is the red dot, which is (1,2). Thus, h=1 and k=2.

To find the radius, you need to use the distance formula. We are given two coordinates: the center (red dot) at (1,2) and a blue dot on the circle at (2.5,4). Find the radius by using the distance formula:

Let (1,2) be x₁ and y₁ and let (2.5,4) be x₂ and y₂. Therefore:

Thus, r is 2.5.

Plugging these numbers into the equation, we have:
