flat roof that is 22�Œ by 36�Œ
cylindrical cistern 12�Œ high and 5�Œ in diameter
Rain falls on a flat roof that is 22�Œ by 36�Œ. The rain drains into a cylindrical cistern 12�Œ high and 5�Œ in diameter. Assume that all of the rain drains into the cylinder (no evaporation or leaks.)
A. How many inches of rainfall will it take to fill the cistern to a depth of 4�Œ6��?
1. Formulas need:
2. Explain how you would approach solving this problem.
3. Show all work needed to find the solution.
B. How many more inches of rain on the roof would cause the cistern to overflow?
