Area = 1/2 of the base X the height
a = 1/2 bh
Perimeter = a + b + c                                                           Video        
(add the length of the three sides)                           Area of a Triangles

                                                Area of Trapezoid
Perimeter = a + b1 + b2 + c
P = a + b1 + b2 + c


The distance around the circle is a circumference. The
distance across the circle is the diameter (d). The radius
(r) is the distance from the center to a point on the circle. 
(Pi = 3.14)

Rectangular Solid( Rectangular prism)Volume = Length X Width X HeightV = lwhSurface area = 2lw + 2lh + 2wh


Volume = Base X Height
Surface = 2b + Ph (b is the
area of the base P is the
perimeter of the base)


pi x square of the radius x height


V = 1/3 bh (1/3 x area of the base x height

b is the area of the base
Surface Area: Add the area of the base to the
sum of the areas of all of the triangular faces.
The areas of the triangular faces will have
different formulas for different shaped bases

Volume = 1/3 pr2 x height
V= 1/3 pr2h
Surface = pr2 + prs
S = pr2 + prs
