What is the standard form of an equation of a circle?
(x+5)^2+(y-2)^2=1.69
(x- h)^2+(y- k)^2= r^2 In this form, ( h, k) is the center of the circle and r is its radius. We are told that the center of the circle is ( - 5, 2) and its radius is 1.3. This information is enough to write the equation. (x-( - 5))^2+(y- 2)^2= 1.3^2 ⇕ (x+5)^2+(y-2)^2=1.69
