Find and interpret perimeter and circumference in numeric and contextual problems.
Compare boundary distances
Problem
Calculate and compare the outside distances of a \(6\text{-}\text{unit}\text{-}by-4\text{-}\text{unit}\) rectangle and a circle with diameter \(8~\text{units}\). Use \(3.14\) for \(\pi~\) if needed.
Big Picture
What this problem is really about
Compare like quantities by finding the full boundary length of each figure. Add both pairs of rectangle sides, use pi times diameter for the circle with the stated approximation, and keep both results in the same linear units. Only after both outside distances are complete should their numerical values be compared.
