Question

What is the equation of the circle below?

Answer 1

`\displaystyle \boxed{x^2 + y^2 = 25}`

Explanation:

Since the center [(h, k)] is at the origin, we do not move, so it stays at
`\displaystyle x^2 + y^2.`Now, the circle equation is
`\displaystyle [X - H]^2 + [Y - K]^2 = R^2,`so since the radius is 5, we square it to get 25. So, with that being said, you have this:

`\displaystyle \boxed{x^2 + y^2 = 25}`

I am joyous to assist you anytime.

Answer 2

Since radius is 5, equation is:

`x^2+ y^2= 5^2\\</p><p>\boxed{x^2+ y^2=25}`
