Question

Could you help me out with a question

Answer 1

The equation of a circle is given by the following formula:

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

Where h and k are the x and y coordinates of the center respectively and r is the radius of the circle. Use the given values and replace in the formula to find the equation of the circle.

h=4

k=3

r=9

`\begin{gathered} (x-4)^2+(y-3)^2=9^2 \\ \end{gathered}`

The equation of the circle is:

`(x-4)^2+(y-3)^2=81`
