Geometry Unit 6, Day 8 Mr. Zampetti Volume of Cylinders Geometry Unit 6, Day 8 Mr. Zampetti

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

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

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

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

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