Find a polar equation that has the same graph as the equation in x and y. x^2 + y^2 = 5

X^2 + y^2 can be replaced by r^2 to obtain the polar equation equivalent to x^2 + y^2 = 5.  Thus, r^2 = 5, and r = sqrt(5).  That's all that's necessary.  No matter what the angle is, r will always be sqrt(5).

It would be 3x+3 because the skate rental is for the day and she spent 3 hours skating. hope this !
