Reply:you cant give ten points. and you cant cover half of a CIRCULAR pond with a water lily because the lily is circular. that is unless there is only half a lily.

LisaC123 - it doubles in size every day, on the thirtieth day it fills the pond, so the day before that it was half the size needed to cover the pond making it 29 days
