What Is The Equation Of A Circle With Center 84 And Radius 7 class=

Answer :

The general equation of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where:

(h, k) are the coordinates of the center.

r is the radius.

In this case:

Center: (8, 4)

Radius: 7

Then, we use the equation of the circle:

[tex](x-8)^2+(y-4)^2=7^2[/tex]

Then simplify:

[tex](x-8)^2+(y-4)^2=49[/tex] The correct answer is option 4
