Length of an Arc Formula

	Trapezoid Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c
	Circle 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.  d = 2r c = pd = 2 pr A = pr2 (p=3.14)
	Rectangular Solid Volume = Length X Width X Height V = lwh Surface = 2lw + 2lh + 2wh
	Prisms Volume = Base X Height v=bh Surface = 2b + Ph (b is the area of the base P is the perimeter of the base)
	Cylinder Volume = pr2 x height V = pr2 h Surface = 2p radius x height S = 2prh + 2pr2
	Pyramid V = 1/3 bh 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.
	ConesVolume = 1/3 pr2 x heightV= 1/3 pr2h Surface = pr2 + prsS = pr2 + prs =pr2 + pr
	SphereVolume = 4/3 pr3V = 4/3 pr3 Surface = 4pr2S = 4pr2

Shapes	Formula
	Rectangle: Area = Length X Width A = lw Perimeter = 2 X Lengths + 2 X Widths P = 2l + 2w
	Parallelogram Area = Base X Height a = bh
	TriangleArea = 1/2 of the base X the height a = 1/2 bh Perimeter = a + b + c (add the length of the three sides
