Circle
Pi = 3.14
Area= pi x r2
Circumfrence= pi x D
R = radius
D= Diameter
Rectangle
Area= Length x Width
Perimeter= 2(Length x Width)
Trapezoid
H= height
B= Base
Area = 1/2 h (b1 + b2)
Triangle
H = Height
B = Base
Area = 1/2 b x h
Cylinder
r= radius
h= heights
pi= 3.14
Volume = pi x r2 x h
Surface area = 2pi x r2 + 2pi x r x h
Parallelogram
b= base
h = height
Area = b x h
Pythagorean theorem
a2 + b2 = c2
Rectangular Solid
l = length
w= width
h= height
Volume= l x w x h
Surface Area = 2wl + 2lh + 2wh
Distance Formula
distance = rate x time
mean: In a collection of data, the sum of all the data divided by the number of data.
Median: The middle number or average of teh two middle numbers in a collection of data when the data are arranged in order.
Mode: the number or numbers that occur most often in a collection of data.
Range: The difference between the greatest and the least nmbers in a collection of data.
Metric Units of Length:
1 kilometer = 1,000 meters
1 centimeter = 0.01 meter
1 millimeter = 0.001 meter
U.S. Unit of Conversions:
8 fluid ounces = 1 cup
2 cups = 1 pint
4 quarts = 1 gallon
16 ounces = 1 pound
5,280 feet = 1 mile
12 inches = 1 foot
3 feet = 1 yard
