Problema Solution
Ralph wants to childproof his house now that his daughter has learned to walk. The round, glass‐ top coffee table in his living room has a diameter of 36 inches. How much soft padding does Ralph need to cover the edges around the table?
Answer provided by our tutors
let
d = 36 in the diameter of the round table
we will assume the table is in a circle shape thus we need to find the perimeter of a circle with diameter d = 36 in:
P = 2*(d/2)*pi
P = 2*(36/2)*pi
P = 36 pi
P = 113.04 in (pi = 3.14)
Ralph needs 113.04 inches of soft padding to cover the edges around the table.
