The equation for the plot of a circle is $x^2+y^2=r^2$ where $r$ is the radius of the circle. On the spreadsheet titled Gircle, generate points for $x=0\mathrm{.}0.\mathrm{.}5\mathrm{.}0$ in increments of $0\mathrm{.}1.$ The user will enter a value for $r$ in cell $F1.$ Calculate values for $y$ using each $x$ and the user given radius. Using $5$ as the radius, plot your results of $x$ vs$.y.($You should see a quarter of a circle.$)$ Label the chart completely. $(10$ points$)$
