Hello!!
![\left \{ {{x = 3 cos t} \atop {y = 3 sin t}} \right. \\\left \{ {{y^2 = (3 cos t)^2} \atop {x^2= (3 sin t)^2}} \right. \\\left \{ {{y^2 = 3^2 cos^2 t} \atop {x^2= 3^2 sin^2 t}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%20%3D%203%20cos%20t%7D%20%5Catop%20%7By%20%3D%203%20sin%20t%7D%7D%20%5Cright.%20%5C%5C%5Cleft%20%5C%7B%20%7B%7By%5E2%20%3D%20%283%20cos%20t%29%5E2%7D%20%5Catop%20%7Bx%5E2%3D%20%283%20sin%20t%29%5E2%7D%7D%20%5Cright.%20%5C%5C%5Cleft%20%5C%7B%20%7B%7By%5E2%20%3D%203%5E2%20cos%5E2%20t%7D%20%5Catop%20%7Bx%5E2%3D%203%5E2%20sin%5E2%20t%7D%7D%20%5Cright.)
Now add them,
![x^2 + y^2 = 3^2cos^2t + 3^2sin^2t \\x^2 + y^2 = 3^2 * (cos^2t + sin^2t) ---> (REMEMBER: cos^2t + sin^2t = 1) \\x^2 + y^2 = 3^2 * 1 \\x^2 + y^2 = 3^2](https://tex.z-dn.net/?f=x%5E2%20%2B%20y%5E2%20%3D%203%5E2cos%5E2t%20%2B%203%5E2sin%5E2t%20%5C%5Cx%5E2%20%2B%20y%5E2%20%3D%203%5E2%20%2A%20%28cos%5E2t%20%2B%20sin%5E2t%29%20---%3E%20%28REMEMBER%3A%20cos%5E2t%20%2B%20sin%5E2t%20%3D%201%29%20%5C%5Cx%5E2%20%2B%20y%5E2%20%3D%203%5E2%20%2A%201%20%5C%5Cx%5E2%20%2B%20y%5E2%20%3D%203%5E2)
Therefore, the center is at the origin
(0,0), and the radius is
3. We eliminated the parameter!
Good luck :)
