GEOMETRIC MATH FORMULAS Rectаngles - Perimeter: The sum оf аll the sides. (2L + 2W) Areа оf a rectangle: length x width Area оf a parallelogram: base x height Area of a trapezoid: h (B+b)/2 or “the sum of the bases, times the height, divided by 2” Triangles - The angles of a triangle = 180 Area of a triangle: b x h divided by 2 Pythagorean Theorem: a squared + b squared = c squared or hypotenuse Circles The radius of a circle is from the center to the perimeter. Diameter/2 Diameter is 2R Circumference is the distance around, π x diameter π = C/D (3.14) Area of a circle: π x r squared Volumes - Rectangle: l x w x h Cylinder: π x r squared x height Sphere: 4 x π x r cubed/3 Cone: π x r squared x height divided by 3 Miscellaneous - 3 x 4 = -12 -3 x (-4) = 12 -36 / 4 = -9 -75/(-3) = 25 PEMDAS = parentheses, exponents, multiply or divide from left to right, add or subtract from left to right American System Length 12 inches = 1 foot 3 feet = 1 yard 5280 feet = 1 mile 1760 yards = 1 mile Weight 16 ounces = 1 pound 2000 pounds = 1 ton Volume 8 fluid ounces = 1 cup 2 cups = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon Metric System 1 kilometer (km) = 1000 meters 1 centimeter (cm) = 0.01 meter 1 millimeter (mm) = 0.001 meter 1 centimeter (cm) = 10 millimeters (mm) 1 kiloliter (kL) = 1,000 liters 1 liter (L) = 1000mL 1 milliliter (mL) = 0.001 liter Converting Temperature Celcius to Fahrenheit F = 1.8 x C + 32 Fahrenheit to Celcius C = 5 x F - 160/9
