Question

the equation for the circle below is x2+y2=100 what is the length of the circle radius

Answer 1

Answer: We are given a circle, and we need to find the length of its radius:

The general equation of a circle is:

$x^2+y^2=r^2$

From this, we can conclude that the radius of the circle is:

$\begin{gathered} r^2=100 \\ \therefore\rightarrow \\ r=\sqrt[]{100}=10 \end{gathered}$
