Question
- a circle has its center at (4, -2) and has a radius of 3. what is the equation of the circle? (x - 4)^2+(y + 2)^2 = 9 (x - 4)^2+(y - 2)^2 = 3 (x - 4)^2+(y + 2)^2 = 3 (x - 4)^2+(y - 2)^2 = 9
Step1: Recuerda la fórmula general
La fórmula de la ecuación de un círculo con centro $(h,k)$ y radio $r$ es $(x - h)^2+(y - k)^2=r^2$.
Step2: Identifica los valores de $h$, $k$ y $r$
Dado que el centro es $(4,- 2)$ entonces $h = 4$ y $k=-2$, y el radio $r = 3$.
Step3: Sustituye los valores en la fórmula
Sustituyendo en la fórmula $(x - h)^2+(y - k)^2=r^2$, obtenemos $(x - 4)^2+(y+2)^2=9$.
