The general equation for a circle is given by:


\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ \text{where:} \\ \text{center}=(h,k) \\ r=\text{radius} \\ \end{gathered}

For this equation:


x^2+y^2=49

We can rewrite it as:


x^2+y^2=7^2

Therefore:

h = 0

k = 0

r = 7

Hence, the answer is:

a circle with center (0, 0) and radius 7
