Question

Find the center and radius of the following circle. Then graph the circle.(×+4)2+y2=7

Answer 1

Given:

Equation of a circle

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

Required:

Find the center and radius of the circle. Then graph of circle.

Step-by-step explanation:

We have a standard equation of circle

`(x-h)^2+(y-k)^2=r^2`

Whose radius is (h, k) and radius r.

We have equation of a circle

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

Now, we will compare with standard equation of a circle

`We\text{ will get center\lparen-4, 0\rparen and radius }√(7).`

Graph of circle is

Answer:

Hence, this is the answer.
