On this circle, a line segment connecting point A to point D is called:
diameter |
|
circumference |
|
chord |
|
radius |
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).
On this circle, line segment CD is the:

circumference |
|
radius |
|
chord |

If a = c = 6, b = d = 7, and the blue angle = 64°, what is the area of this parallelogram?
| 27 | |
| 24 | |
| 42 | |
| 32 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 6 x 7
a = 42
The dimensions of this cylinder are height (h) = 5 and radius (r) = 4. What is the volume?
| 20π | |
| 75π | |
| 80π | |
| 25π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(42 x 5)
v = 80π
