If BD = 11 and AD = 14, AB = ?
| 4 | |
| 3 | |
| 18 | |
| 16 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDIf side x = 11cm, side y = 10cm, and side z = 9cm what is the perimeter of this triangle?
| 36cm | |
| 29cm | |
| 30cm | |
| 26cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 11cm + 10cm + 9cm = 30cm
If the length of AB equals the length of BD, point B __________ this line segment.

trisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
The dimensions of this cylinder are height (h) = 3 and radius (r) = 7. What is the volume?
| 448π | |
| 6π | |
| 54π | |
| 147π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 3)
v = 147π
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h2 x l2 x w2 |
|
2lw x 2wh + 2lh |
|
lw x wh + lh |
|
h x l x w |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
