Sagot :

Answer:

D. 6

Explanation:

The general equation for a circle centered at the origin (0,0) is:

[tex]x^2+y^2=r^2[/tex]

Given the equation of the circle:

[tex]\begin{gathered} x^2+y^2=36 \\ \implies r^2=36 \\ r^2=6^2 \\ r=6 \end{gathered}[/tex]

Thus, the radius of the given circle is 6.
