This is what i have so far(adsbygoogle = window.adsbygoogle || []).push({});

SA = 2(pi)r^2 + 2(pi)r(245.45 / (pi)r^2)

Derivative of SA = - 490.9r^2 + 4(pi)r

0 = -490.9r^2 + 4(pi)r

and i'm stuck at this step.. i've tried a bunch of things to try and solve for r but i can't seam to get a logical answer for the radius of the minimized pop can
