MA.7.GR.2.2 · Geometric Reasoning
Students solve real-world problems involving the surface area of right circular cylinders, such as how much label paper wraps a soup can or how much paint covers a cylindrical tank. Many contexts use only part of the surface, so students first decide which faces actually count.
FAST items are word problems answered through the equation editor. The judgment being tested is which surfaces to include: an open-top container has one base rather than two, and a wraparound label covers only the lateral surface.
These come straight from Algebro's 7th grade question bank, easiest first. Answer one, check it, then move to the next.
