2. Tasks for Today
Warm up
Lesson Vol. of Cylinders!
Begin HW?

3. Warm Up (no calculator!)
What is the slope of the line represented by the equation
What is the y-intercept of the line represented by the equation 2 3
y = x - 4 2 3
y = x - 4
Solve the equations.
b + 45 = 3(b -15)
(w - 6) = 3(w + 1)

4. More Warm Up…

6. We skipped this part of 2.1! 
V = (3.14) (r) (r) (h)

7. The cylinder with the larger base has a larger volume
The cylinder with the greater height has a smaller volume.

8. Suppose that a cylinder has a radius of 5 cm and a height of 12 cm.
What is the area of the base? (B)
B = (3.14) 5 x 5
V = 78.5 x 12
= 942 cubic cm
What is the volume of the cylinder?
What is the formula for volume of a cylinder?

9. Begin HW : p. 83, #3, 4 – volume only, 7a, 30 – 34
The cylinders have different areas of the base (B) and different heights, so the volumes will be different.
So… if you build 2 cylinders from the same rectangle, the one with the larger base will have the greatest volume.
