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.
If AD = 19 and BD = 10, AB = ?
| 9 | |
| 4 | |
| 8 | |
| 15 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDThe dimensions of this cylinder are height (h) = 5 and radius (r) = 1. What is the volume?

The volume of a cylinder is πr2h:
v = πr2h
v = π(12 x 5)
v = 5π
If a = c = 4, b = d = 5, what is the area of this rectangle?
| 2 | |
| 20 | |

The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 4 x 5
a = 20
