Presentation transcript:

Bell Ringer Find the surface area of each figure. SA = 2lw + 2lh + 2wh SA = 2(4*2) + 2(4*3) + 2(2*3) SA = SA = 52 units² SA = Area of Base + 4 (1/2(b)(h) SA = 7*7 + 4 (1/2)(10*7) SA = SA = 189 units²

3.14 Surface Area: Cylinders and Cones Cylinder : a solid with two congruent parallel circles as bases, joined by a curved, smooth lateral face

1. Draw the net for a cylinder. 2. What are the length and the width of the rectangle that is formed when you unroll the cylinder? Length = circumference/perimeter Width = height

1. Cylinder 2. Triangular prism What is the lateral surface area formula for both a prism and a cylinder? LA = Perimeter of circle/triangle * height P=perimeter/circumference

3. 56 in², 88 in² ft², 344 ft² π in², 88 π in² ft², 344 ft²

Is a cone a polyhedron? Cone: a solid with one base that is a circle, and a curved lateral surface comes to a point. No, because it has a curved lateral surface area.
