The surface area of the balloon is
.
Differentiate both sides with respect to an arbitrary variable representing time:
Meanwhile, the volume of the balloon is
.
Differentiating with respect to
yields
You're told that, at the point when the radius
, the volume of the balloon increases at a rate of
, which means
. Use this to solve for the rate of change of the radius,
.
Substitute this into the equation for the rate of change of the surface area and solve for
.
