The dimensions of this cube are height (h) = 2, length (l) = 3, and width (w) = 4. What is the volume?
| 175 | |
| 24 | |
| 108 | |
| 56 |
The volume of a cube is height x length x width:
v = h x l x w
v = 2 x 3 x 4
v = 24
Breaking apart a quadratic expression into a pair of binomials is called:
deconstructing |
|
squaring |
|
normalizing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The dimensions of this cylinder are height (h) = 9 and radius (r) = 3. What is the volume?
| 81π | |
| 252π | |
| 20π | |
| 125π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(32 x 9)
v = 81π
On this circle, a line segment connecting point A to point D is called:
diameter |
|
radius |
|
chord |
|
circumference |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
A right angle measures:
180° |
|
360° |
|
90° |
|
45° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.
