Task# Measuring the area of a circle

Illustrative MathematicsVaries

This goal of this task is to give students familiarity using the formula for the area of a circle while also addressing measurement error and addresses both 7.G.4 and 7.RP.3. Students might find it confusing to be asked to find the area of the cross-section of the pipe since looking at the cross section, it is 'empty' in the middle. It is common for students to get confused about which parts of the figure are part of the circle itself.
