    yes r is 8 its based off the formula x^2+y^2=8

    i think its the last one r^2=64 r=8

    x^2+y^2=8 ==> r^2=8

    how can r^2 be both 8 and 64?

    8^2=64

    no but when you are converting to a polar equation \[r=\sqrt{x^2+y^2}\]

    therefore \[r^2=x^2+y^2\]

    so you are replacing the \[x^2+y^2 \]

    with \[r^2\]

    yes you are converting from a rectangular equation to a polar equation

    that's what is stated in the question to do

    but if you teacher wants r itself then r is \[r=2\sqrt{2}\]

    r cant be 4 because you have are taking the root of 8 not halving it
