    what is the formula for area and circumference?

    circumference of a circle is \(C=2\pi r\) where \(r\) is the radius

    area is \(\pi r^2=36\pi\) so \(r=?\)

    not \(36\div 2\) but rather \(\sqrt{36}\)

    area is \(\sf\pi r^2=36\pi \to r^2 = 26\)

    right, and if \(r=6\) then your final job is to compute \[2\times 6\times \pi\]

    and now plug in \(\sf r=6\) into the circumference formula (:

    You don't simplify the \(\sf\pi\) since it wants the exact circumference
