**DrBob222**, Tuesday, November 25, 2008 at 1:23pmThe area of John's back yard garden will be A = pi*r^2 where r = radius = 1/2 the diameter.

Then set up a proportion as follows:

(1 bag/90 ft^2)=(x bags/area garden)

solve for x bags. The answer I obtained is 2.23 bags; therefore, John must buy 3 bags.
