A circle is a set of points in a plane equidistant
from a fixed point. It has a general formula of x² + y² = r². This is if the
center is at the origin. However, if the center at point h and k, the
equation becomes (x-h)² + (y-k)² = r².<span>
We write the given equation in the
form (x-h)² + (y-k)² = r² by completing the square.

<span>x</span>²<span> + y</span>²<span> + 10x – 6y + 18 = 0</span>
<span>
(x² + 10x + 25 )+ (y² - 6y + 9) = −18 + 25 + 9 = 16
(x + 5)² + (y + 3)² = (4)²
Therefore,
center = (-5, -5)
radius = 4</span>

Answer:
<h2> 8.06ft</h2>
Step-by-step explanation:
step one:
This problem is on the mensuration of solids,
given that the area is 65ft^2
step two:
we know that the expression for the area of a solid is
areaa= length* length
area= l^2
step three:
substituting the value of the area into the expression we have
65=l^2
we need to square both sides to solve for l we have
√65=l
l= 8.05ft
step four:
From the analysis we found the length of one side to be 8.06ft
