hey guys. :) how are you? its me Steph.

As always, Mr. P starts our class by giving us activities. This time he asks us to bring popcorns. He told us to bring out 2 loss leafs. We'll make a cylinder, one is folded horizontally then the other one is folded vertically. The challenge is we need to find out which popcorn bag has more popcorns inside without using any mathematical calculation. So to find out, we need to put the taller popcorn bag inside the short one, fill the taller bag with popcorn and remove it inside the short bag and because of that we find out that the shorter one has the larger amount of popcorn inside..


   The next thing we did was we talked about how to get the volume of a right circular cylinder. We proved that the short popcorn bag has the more popcorn inside using formulas.


 Mr.P also gave us worksheet where in we will find the surface area or the volume of the given figure. We answered some numbers. And thats what we did last Tuesday :) :)
