3. Cylinder
Remember:
A cylinder is a 3D figure with two circular bases

4. Surface Area of a Cylinder
Formula for Surface Area:
S = 2prh + 2pr2

5. Example #1
Calculate the surface area and leave your answer in terms of :
S = 2pr2 + 2prh
S = 2()(6.5)2 + 2()(6.5)(6)
S =162.5 ft2

6. Volume of a Cylinder
Formula for Volume:
V = pr2 h

7. Example #2 Calculate the volume and leave your answer in terms of :
V = pr2h
V = ()(6.5)2(6)
V = 253.5 ft3
