Answer:

The center is:
(2, -4)
Step-by-step explanation:
We have the following equation

The general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1

<u>Step 2</u>
<u> </u>Add and subtract
For an equation of the form


<u>Step 3 </u> Factor the expressions within the parentheses

<u>Step 4 Simplify</u>


Finally

The center is:
(2, -4)
A calculator can help you with that.
In radians, arcsin(sin(9π) / 7) = 0.
