A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The endpoints of this line segment are at (-2, 8) and (2, 0). What is the slope of this line?
| -1 | |
| -2 | |
| -\(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\) |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 8) and (2, 0) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(0.0) - (8.0)}{(2) - (-2)} \) = \( \frac{-8}{4} \)Order the following types of angle from least number of degrees to most number of degrees.
right, acute, obtuse |

acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
The dimensions of this cylinder are height (h) = 3 and radius (r) = 7. What is the volume?
| 7π | |
| 405π | |
| 147π | |
| 81π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 3)
v = 147π
If a = c = 6, b = d = 9, what is the area of this rectangle?
| 54 | |
| 8 | |
| 35 | |
| 40 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 6 x 9
a = 54
