Aim: How do we find surface area and lateral area of prisms and cylinders?

Prisms is a solid with bases that are 2 congruent polygons. The other sides of the prisms are called the lateral faces.

Surface Area : Lateral area + area of the two ends(bases)
Lateral area: Perimeter of the base*height
Surface area : perimeter of base* height + 2(Area of the base)

Cylinders


Surface Area: Areas of top and bottom +Area of the side
Lateral area: 2*pi*r*h
Surface area: Surface Area = 2(pi r ²) + (2 pi r)* h

WHAT IS THE SURFACE AREA OF A SPHERE?

how do we do compositions of transformations?

• Compositions of transformations are when 2 or more transformations are combined to form a new transformation.
• In a composition, you do the second one FIRST.
