Question

Write an equation of the circle with center(9,-39) and radius 6

Answer 1

Answer:

Given a circle of radius r=5

Given center lies on x-axis.  

So, let the center be (h,0)

Equation of circle is

(x−h)

=25       ....(1)

Since, it passes through (2,3)

⇒(2−h)

=25

⇒(2−h)

=16

⇒2−h=±4

⇒h=−2,h=6

When h=−2, the equation of circle is  

(x+2)

+y

=25

⇒x

=25

⇒x

+4x−21=0

When h=6, the equation of circle is  

(x−6)

=25

⇒x
