Question

Find the equation for the circle with center (3,-5) and diameter of length 8.

Answer 1

Answer:

given,

diameter = 8

=> radius = 4

center = (3,-5)

equation of circle is

(x-3)^2 + (y-(-5))^2 = 4^2

x^2 + y^2 - 6x +10y+34 = 16

therefore equation of circle is

x^2 + y^2 - 6x + 10y +18
