SOLUTION: Find the radius of the circle defined by the equation: 5x^2+5y^3+60x+40y+215=0. It tells me that the standard form of the equation of a circle is (x-h)^2+(y-k)^2=r^2 , but how do

Question 376188: Find the radius of the circle defined by the equation: 5x^2+5y^3+60x+40y+215=0.
It tells me that the standard form of the equation of a circle is (x-h)^2+(y-k)^2=r^2 , but how do I go about putting this equation into standard form? I'm a bit confused please help.
