Acircular table has a diameter of 4ft. what is its approximate area? (use pi=3)

Good question if only because it approximates. I imagine you might have been told to do the question in your head.

Area = pi r^2
r = d/2
r = 4/2
r = 2 feet
pi = 3

Area = 3 * 2 * 2 = 12 square feet <<<<<< Answer.

Somewhere in 1 Kings Ch 7, the Bible makes reference to pi being 3. It's a pretty good estimate considering the number system the Bible used. 

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
