Q:
# The circle below is centered at the origin and has a radius of 5. What is its equation?

Accepted Solution

A:

[tex]\bf \textit{equation of a circle}\\\\
(x- h)^2+(y- k)^2= r^2
\qquad
center~~(\stackrel{0}{ h},\stackrel{0}{ k})\qquad \qquad
radius=\stackrel{5}{ r}
\\\\\\
(x-0)^2+(y-0)^2=5^2\implies x^2+y^2=25[/tex]
