### Scribe for Monday

Given f(x)=0.5x^2-2x+4

And g(x) = 2 + rt 4+4x-x^2

S is the region between f and g, write the interval that gives:

a) The volume generated by rotating s around the line y=5.

b) The Volume generated by rotating s around the line y=1.

c) The volume generated by rotating s around the y-axis.

Rotating two lines, It surface will be looks like a washer.

And the Volume of a cylinder V = pai (R^2-r^2)

a)---> pai

pai

b)---> pai

c)---> Pai

A roll of paper towels has dimesions

Find the volume of the papper

Volume of Pai r^2 h a cylinder

V = Pai h (R^2-r^2)

= pai h (R+h) (R-h)

(circle) (height) (width)

I like that you've included the problems we did. I

reallylike to read about how the class was in your own words. How would you describe what was learned? Maybe even mention something about the quizzes that will be happening at the begining of each class. How about a countdown to the exam?Here, let me start it ....

20 classes left until the exam.
