Question

Can you solve this plz
Find the equation of the circle with centre C and radius r where:
C=(-7,-3),r=4​

Answer 1

Answer:

The equation of circle with center (a,b) and radius r is

(x - a)^2 + (y - b)^2 = r^2

In your question, a=(-7) and b=(-3) and r= 4

So, equation of circle is

(x + 7)^2 + (y + 3)^2 = (4)^2

By simplification,

x^2 + y^2 + 14x + 6y + 42 = 0
