Question

A circle is centered at (2, -5) and has radius 3. Write its equation in standard form.

Answer 1

for a given centre of (h,k) and radius r, the equation is

(x-h)^2 + (y-k)^2 = r^2

use your information to form the equation.

Answer 2

(x-2)^2+[y-(-5)]^2=r^2

(x-2)^3+(y+5)^2=3^2



(x-2)^3+(y+5)^2=9
