Where can I purchase the 1/2 inch spheres for Design Problem 3.3?
As this is the global Canvas community, made up of people like you who use Canvas, we don't have access to your course or to the specific problem you are referencing. I'd suggest contacting your course instructor. That should be possible through the "People" tab in your course, or by clicking on Help in the left sidebar and then selecting "ask my instructor a question" (or similar).
