Warm UP 4/13 Find the surface area of the following figures: A cylinder with the height of 14 cm and a base radius of 2.3 cm cm SA=Ph+2B P=(6)(6)=36 h=17 B=1/2ap =1/2(5.19)(6) =15.57 SA=36(17)+2(15.57) = cm squared

Announcements Quiz next Tuesday Homework due tomorrow Warm ups due tomorrow

Prisms and Cylinders Cylinder: a solid with two congruent circular bases that are parallel. other sides are called __________________________ faces.

Surface Area of a Right Cylinder

Example Find the lateral and total surface area of the cylinder below: Lateral 2πrh =2 π(4)(8) =64 π cm squared

Applying Lateral Area of a Cylinder Find the lateral area A=2πrh r=1.25 in h=6 A=2π(1.25)(6) =15 π inches squared
