the area of a circle is πr^2
So, to convert that to time,
6.25π m^2 * 28min/1m^2 = 549.778 min
assuming that the entire circle is covered by grass.
A goat is tied by a rope 2.5m long to a peg in some grass. The goat eats 1sqm of grass in 28 minutes. How long does it take to eat all that it can reach?
