Acircle in the xyxyx, y-plane has the equation 36x^2+36y^2-12x-27y-8=036x 2 +36y 2 −12x−27y−8=036, x, start superscript, 2, end superscript, plus, 36, y, start superscript, 2, end superscript, minus, 12, x, minus, 27, y, minus, 8, equals, 0. how long is the radius of the circle?

we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient of each expression

Complete the square twice. Remember to balance the equation by adding the same constants to each side.

Rewrite as perfect squares

Divide both sides by 36

the radius of the circle is equal to

r=0.625 units

the answer is

the radius is equal to r=0.625 units
