It is important to combine two formulas because once you solve for one you can substitute in the answer to solve the next equation. If I were to connect this same skill to my can I would be able to find my height and substitute it in, in order to find the surface area of my can.
1. "you can substitute in the answer to solve the next equation" - What does this do with the height variable in the surface area function?
ReplyDelete2. "find my height" sounds like you're finding one height instead of the height formula. Where are you substituting the height formula into?
