Answer:

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

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
√(100) units=10 units.
