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 = 2rh + 2r2

Example #1 Calculate the surface area

and leave your answer in terms of :

S = 2r2 + 2rh

S = 2()(6.5)2 + 2()(6.5)(6)

S =162.5 ft2

Volume of a Cylinder

Formula for Volume:

V = r2 h

Example #2 Calculate the volume and leave

your answer in terms of :

V = r2h

V = ()(6.5)2(6)

V = 253.5 ft3
