7. What is the equation of a circle with a
center of (-5, 3) and a radius of 4?
A. (X - 5)2 + (y + 3)2 = 16
B. (x + 5)2 + (y - 3)2 = 16
C. (x - 5)2 + (y + 3)2 = 2
D. (x + 5)2 + (y - 3)2 = 2

Respuesta :

Answer:

equation of circle is (x+5)^2+(y-3)^2=16

Step-by-step explanation:

equation of circle [tex](x-x_1)^2+(y-y_1)^2=r^2

where r=redius of circle,[tex](x_1,y_1)[/tex] is centre of circle

centre of circle=(-5,3)

put the value of centre and redius in the equation

equation of circle [tex]{(x+5)^2+(y-3)^2}[/tex]=4^2
