Step 1:

The circle equation $\"\"$

Convert the equation into standard form of circle $\"\"$

Where $\"\"$ is center and $\"\"$ is radius of circle.

$\"\"$

Change the expreession $\"\"$ into a perfect square trinomial add (half the x coefficient)² to each side of the equation.

$\"\"$

Divide each side by 5.

$\"\"$

Compare with standard form of circle $\"\"$ .

$\"\"$

Solution:

Standard form of the circle is $\"\"$ .

Radius is $\"\"$ units.
