2 answers:
Answer:
center of the circle is (-4,6)
Second option is correct.
Step-by-step explanation:
The given equation of circle is
The general form of a circle is given by the equation
Here (h,k) is the center and r is the radius.
On comparing the equation with this general form, we get
h = -4, k = 6
Therefore, the center of the circle is (-4,6)
Second option is correct.

Answer: The length of the square is
Step-by-step explanation:
By definition, the area of a Regular polygon can be calculated with the following formula:
Where "s" the length of any side of the polygon and "n" is the number of sides .
According to the information given in the exercise, you know that:
Since an hexagon has six sides, you know that:
Therefore, its area is:
The formula to find the area of a square is:
Where "s" is the length of any side of the square.
Since that regular hexagon has the same area as this square, you can substituting the area calculated above into the formula for calculate the area of a square, and then solve for "s".
Then you get:
