### Josiah Rudolph

## 10.1 area of parallelogram and trapezoids

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

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 10.3 Equations In Two Variables

## 10.3 Three-dimensional figures

the formula is V=pi*r^2*h

A cone's formula is V=1/3*pi*r^2*h

The formula for a sphere area is A=4*Pi*r^2

## Soup can another example of some of the things we eat and what it comes in | ## Cone Build en are houses may have a cone on it | ## Death Sphere The whole Earth is one big sphere same with all the planets in space |

## Chapter 10.4 Surface Area of Prisms and Cylinders

## surface area and nets

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

The formula for slant height is

Example

S=B+1/2*P*l

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

S=99.7
