(Solved): Need help answering the two questions highlighted in blue please Define radius r=3; Define x and y ...

Define radius $r=3\text{; }$ Define $x$ and $y$ in terms of theta and $r$ $\begin{array}{l}x=r^{?}\cos (\text{ theta) }\\ x=1\times 7\\ \begin{array}{lllllll}3.0000& 2.5981& 2.1213& 1.5000& ?1.5000& ?2.1213& ?2.4271\end{array}\end{array}$ $\begin{array}{l}y=r^{?}\sin (\text{ theta) }\\ y=1\times 7\\ \begin{array}{lllllll}0& 1.5000& 2.1213& 2.5981& ?2.5981& ?2.1213& ?1.7634\end{array}\\ r=\mathrm{sqrt}\left(x,{}^{?}2+y?{}^{?}\right)\\ r=1\times 7\\ \begin{array}{llllll}3.0000& 3.00003.0000& 3.0000& 3.0000& 3.0000& 3.0000\end{array}\end{array}$ Check that $x$ and $y$ satisfy the equation of a circle See r above Explain results here. Do $x$ and $y$ satisfy the equation of a circle? Why or why not? How does the vector output at the end confirm your answer?
