Box information and Reference

  A cube is a three-dimensional figure with six matching square sides. In a rectangular box, the length, width and height may be of different lengths.
 
    l = length of box
    w = width of box
    h = height of box

  SpeedCrunch colors the expression according to the syntax. You can easily distinguish numbers from variables. You can also see the matched parentheses.
 

fig. 1  Box Volume
   Volume = l*w*h
   Surface Area = 2*(l*w+l*h+w*h)

 Pyramid Information and Reference
   A pyramid is a solid with a polygon base and connected by triangular faces to its vertex. A pyramid is a regular pyramid if its base is a regular polygon and the triangular faces are all congruent isosceles triangles.
    l = length of base
    w = width of base
    h = height of pyramid

  c and d = slant height of pyramid face (c= length face & d = width face)

  SpeedCrunch has unlimited variable storage and more than 50 built-in math functions.

fig. 3  Pyramid Volume and Surface Area
   Volume = l*w*h/3
   Surface Area = l*c+w*d+l*w
   c=√((w/2)²+h²)    d=√((l/2)²+h²)

 Topless Pyramid Information and Reference

  A trunctated pyramid volume is one third the height times (A + sqrt(A*B) + B) where A and B are the area of the top and bottom faces.
  A= area (A*B) and B= area (C*D)

  In SpeedCrunch variables need not be only a character, "InterestRate" is a perfect name as well. And still, you can define as many variables as you want.
  There is a special variable, ans, which always holds the last calculation result.
  

fig. 5  Topless Pyramid Volume and Surface Area
   Volume = (h/3)((a*b)+(c*d)+√((a*b)(c*d)))
   Surface Area = x+y+u    u=(a*b)+(c*d)
   x= 2*(a+c)*h/2    y= 2*(b+d)*h/2

 Cylinder Information and Reference
  A cylinder is a solid with two congruent circles joined by a curved surface.

  The expression: v = π*r²*h:
  Speed Crunch  does not use implied multiplication. For multiplication you need to include the multiplication operator.

    r = radius of cylinder
    h = height of cylinder

  In SpeedCrunch you do not need to memorize function names, use Ctrl+F to pop up a dialog where you can choose the function that you need.

fig. 7  Cylinder Volume & Surface Area
   Volume = π*r²*h
   Surface Area = 2*π*r(r+h)
  Note: 2πr*(r+h) = 2*πr² + 2*π*r*h

 Cone Information and Reference
   A circular cone has a circular base, which is connected by a curved surface to its vertex.
The vertex is the top or pointed area of the cone.

    r = radius of cone base
    h = height of cone
    l = slant height of cone (see diagram)
    l = √(r²+h²)

  Total Surface Area = Lateral Surface Area + Base Area
  Lateral Surface Area = π*r*√(r²+h²)
  Base Area = π*r²
  Total Surface Area = π*r²+π*r*√(r²+h²)

fig. 9  Cone Volume and Surface Area
   Volume = π*r²*h/3
   Surface Area = π*r²+π*R√(R²+h²)

 Topless Cone Information and Reference

 L= Lateral Surface Area:
   L= pi*(R1+R2)*sqrt((R1-R2)^2+h^2)
 A= Total Surface Area
   A= pi*(R1+R2)*sqrt((R1-R2)^2+h^2)+pi*(R1^2+R2^2)
 V= Volume
   V= (pi*h/3)*(R1^2+R2^2+(R1*R2))
 
 Topless Cone = Cone Frustum
 Topless Cone = Truncated Cone

fig. 11  Topless Cone Volume
   Volume = πh/3(R1²+R2²+R1R2)
   Surface Area = π(R1+R2)√((R1-R2)²+h²)+π(R1²+R2²)

 Sphere Information and Reference

A sphere is a solid with all its points equal distance from the center.


      r = radius of sphere

  In SpeedCrunch you just type the expression that you want to calculate and press Enter. You can see clearly what you typed along with the result in the scrollable display.

fig. 13  Sphere Volume and Surface Area
   Volume = 4/3πr³
   Surface Area = 4πR²

 Sphere 2 Base Segment Information and Reference

 
 a= large radius of segment
 b= small radius segment
 h= height of segment
 R= radius of sphere

  In SpeedCrunch you can paste the expression from the clipboard, that you copied from somewhere else. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R.

  In geometry, a spherical cap is a portion of a sphere cut off by a plane.   The expression: A = 2*π*r*h:
     R = radius of sphere
     h = height of cap
     a = radius of the cap (or plane)

SAT Test - Math
SparkNotes SAT Polygons
   Good news: Most polygons on the SAT have just four sides. You won’t have to tangle with any dodecahedrons on the SAT you take. There are five different types of quadrilaterals that pop up on the test. These five quadrilaterals are trapezoids, parallelograms, rectangles, rhombuses, and squares.
SparkNotes SAT Circles
   A circle is the collection of points equidistant from a given point, called the center. A circle is named after its center point. The distance from the center to any point on the circle is called the radius, (r), the most important measurement in a circle.
SparkNotes SAT Triangles
   Triangles pop up all over the Math section. There are questions specifically about triangles, questions that ask about triangles inscribed in polygons and circles, and questions about triangles in coordinate geometry.
