11.4 Exit Slip 4.27.10

The most important concept of Tuesday's lesson was being able to find the height using the given radius and Volume. The mathematical tools I used were both a calculator and the computer. The calculator to plug in the expression to get the height of my can. the computer to go on google docs; create a new spread sheet and graph the answers I got for the heights. The graph had to be titled Radius v.s Height. these two tools helped me very much because I wouldn't have to do all the problems hand written because it would've taken too much time. This made my job easier by keeping me more calm and not under pressure because I wasn't going to have to do every problem manually to get the heights.

Today as a class we made sure every one understood how to measure their can and made sure they measured more than one time to find the Diameter. I was able to accomplish finishing my worksheet that involved find the diameter of the Davis Baking Powder as well as the radius then finding the Volume using the formula which was TTr^2*h ; I was also responsible for finding the surface area using the following formula 2TTr^2+ 2TTrh . Knowing the formulas I had to then fill in r with my calculated radius and so on. There isn't a skill I necessarily learned but I did notice that sometimes you have to keep measuring things because your first measurement might not be as accurate as it would be if you try it 3 or 4 times. I'll be able to use this out of school because you never know when you have to measure something any place you go. As of now I understand what's going on Im not lost in any part right now but if any question pop-up anytime soon I will surely ask you. :)
