2. Surface Area and Volume of Cylinders Mr. Bench PVMS

3. Objectives 1. Identify the parts of a. cylinder 2. Find the lateral area, total. surface area and volume. of a cylinder.

4. Cylinder Parts Bases - formed by 2 congruent circles. Axis - The segment connecting the centers of the two bases.

5. T = Lateral + Bases HEIGHT Circumference T =  r h + r2r2  r 2  r 2 Radius LATERAL

6. Surface Area = 104  or 326.56 T = 2  rh + 2  r 2 T = 2  (4)9 + 2  (16) Find the surface area of the cylinder. 4 9

7. Volume The amount of space in a figure V = Bh  16(9) V = (  r 2 )h 9 4 144  or 452.4 units 3

8. Volume V = Bh V = (  r 2 )h V = (4.5 2  )15 V = 303.75  V = 954.3 units 3 9 15
