Scribe Post, December 4th, Jordan

So today we continued going over Chapter 9, Which is the Volume chapter. We started off with daily quiz #33. which was about the volume of a sphere. Once we were finished with that we went over daily quiz #32. daily quiz #32 was, if you have a sphere with a radius or 6 in a box and its touching all sides what is the volume of the space not taken up by the sphere. So to start this problem you have to find the volume of the box and the volume of the sphere. Drawing a picture first usually helps.

volume of a sphere: Volume of a cube:

V=4/3(pi)r^3. V=b*w*l

V= 4/3(pi)216 V=12*12*12 (radius is 6 & the diameter is 2(r) & 2*6=12 &the diameter=l,b&w)

V=288(pi) V= 1728

V=904.78

Volume of the cube-Volume of the sphere=left over volume

1728 - 904.78 = 823.22 units^3

Then we went over the answers for the homework that our classmates did and check to see if they were correct or if we had messed up in making the problems. After that we talked breifly about Tuesdays test and then were dismissed.

next scribe is Christian.
