Water bubbles up at a rate of 1 cm^3/s, forming a circular

[Tascja]

How would i go about solving this:

Water bubbles up at a rate of 1 cm^3/s, forming a circular pond of depth 0.5 cm in his yard. How quickly is the surface area of the pond covering his lawn?

A good place to start would probably be with the formula for the volume of a right circular cylinder, along with the formula for the area of a circle.
