Final answer:

The equation of a circle with center at the origin and radius 6 is x^2 + y^2 = 36.

Step-by-step explanation:

The equation of a circle with center at the origin and radius 6 can be written as:



x2 + y2 = r2



Substituting r with 6:



x2 + y2 = 62



Simplifying the equation:



x2 + y2 = 36

Answer:


\sf \textsf{Equation of a circle} = x^2 + y^2 = 36

Step-by-step explanation:

The equation of a circle with center
\sf (h, k) and radius
\sf r is given by the formula:


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

In this case, since the center is at the origin
\sf (0, 0) and the radius is
\sf 6, the equation becomes:


\sf x^2 + y^2 = 6^2

Simplifying further:


\sf x^2 + y^2 = 36

So, the equation of the circle with center at the origin and radius
\sf 6 is
\sf x^2 + y^2 = 36.
