A right angle measures:
360° |
|
180° |
|
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.
What is the area of a circle with a radius of 5?
| 36π | |
| 6π | |
| 25π | |
| 9π |
The formula for area is πr2:
a = πr2
a = π(52)
a = 25π
Order the following types of angle from least number of degrees to most number of degrees.

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
If a = c = 6, b = d = 2, and the blue angle = 73°, what is the area of this parallelogram?
| 7 | |
| 6 | |
| 12 | |
| 63 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 6 x 2
a = 12
The dimensions of this cylinder are height (h) = 3 and radius (r) = 6. What is the volume?
| 448π | |
| 63π | |
| 64π | |
| 108π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(62 x 3)
v = 108π
