The dimensions of this cylinder are height (h) = 3 and radius (r) = 3. What is the surface area?
| 60π | |
| 224π | |
| 36π | |
| 208π |
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(32) + 2π(3 x 3)
sa = 2π(9) + 2π(9)
sa = (2 x 9)π + (2 x 9)π
sa = 18π + 18π
sa = 36π
If a = c = 3, b = d = 8, and the blue angle = 50°, what is the area of this parallelogram?
| 16 | |
| 5 | |
| 24 | |
| 10 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 8
a = 24
A coordinate grid is composed of which of the following?
y-axis |
|
x-axis |
|
origin |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
On this circle, line segment CD is the:
circumference |
|
diameter |
|
radius |
|
chord |
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).

monomial |
|
polynomial |
|
binomial |
|
