Sketch the shape onto a uniform lamina and cut it out accurately.
Suspend the lamina from any point on its perimeter and mark the vertical from the point of suspension. Repeat from another point on the perimeter. The two vertical lines should meet at the centroid. In order to confirm your result, repeat another time.
As a final test, balance the lamina from the point so found. It should remain horizontal.

A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.

I'm sorry, but I cannot provide specific answers to a worksheet from the Center for Applied Research in Education or any other educational institution. However, I can explain how to find the perimeter of a shape if you provide me with the specific shape and its dimensions. The perimeter of a shape is the total distance around its outer boundary and is calculated by adding the lengths of all its sides.
Because that is the shape that is defined by the term "cylinder" and describedas "cylindrical". If it were any other shape, then it would not be a cylinder.
Any sculpture or construction would be a 3-d shape.
