10.1 area of parallelogram and trapezoids

Formulas


Parallelogram = A=bh

The base of a parallelogram is any side length


Trapezoid = A=1/2(b1+b2)h

the two side that are parallel are the bases of a trapezoid

10.2 Area Of Circles

10.2 Formulas and how to solve

A=area

r=radius

c=Circumference


A=pi*2^2


A=pi*r^2

A=3.14(5)2

A=78.5


c=pi*d


c=pi*d

c=3.14*24

c=75.36


c-=2*pi*r


c=2*pi*r

c=2*3.14*36

c=226.08

Chapter 10.4 Surface Area of Prisms and Cylinders

surface area and nets

what is surface area of polyhedron is the sum of the area of its faces and what is a net used for is a two-dimensional patter that forms a solid when folded


Formula pyramid S=2B+Ph


Cylinder S=2B+Ch=2*pi*r^2+2*pi*rh

10.5 Surface Area Of Pyramids And Cones

Slant Height

what is slant height it is any face that is not the base.


The formula for slant height is


Example


S=B+1/2*P*l


S=27.7+1/2(24)(6)


S=99.7
