A box holds three circular flower pots, each with the same diameter. What is the exact area of the base of one pot? Show your work.( the length of the box is 15 in.)

19.635 square inches.

Assuming that the pots are arranged in a straight line, each pot would have a diameter of 5, because 5 • 3 = 15, and 15 is the length of the box. The radius of the base of one pot is therefore 2.5.
A = pi • r^2 = pi • 2.5^2 = 19.635 (approximation)
