Convert the given Cartesian equation to a polar equation. (Use the following as necessary: r and 6.) X2+y2=25 r = 0,25 008(6) X Recall that polar equations are written in terms of r and 9. Recall the relationship between X, y, and r with respect to the Pythagorean Theorem. Comparing the given equation to the previous relationship what value is equal to r2. What algebraic manipulations are required to isolate r
