Answer:

The center of the circle is (13.4, - 2.6).

Step-by-step explanation:

Circle:

The diameter of a circle is 2 times of its radius.
The area of a circle is $\pi r^2$ , where is the radius of the circle.

The circumference of a circle is $2\pi r$ , where r is radius of the circle.

We know that,the equation of circle is in the form

$(x-\alpha)^2+(y-\beta)^2= r^2$

where $(\alpha, \beta)$ is the center of the circle and r is the radius of the circle.

Given equation of circle is

$(x-13.4)^2+(y+2.6)^2=100$

The center of the circle is (13.4, - 2.6).

The radius of the given circle is $\sqrt{100}$ units=10 units.
