The dimensions of this cylinder are height (h) = 9 and radius (r) = 9. What is the volume?
| 20π | |
| 729π | |
| 5π | |
| 486π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(92 x 9)
v = 729π
What is 8a5 - 2a5?
| a510 | |
| 6a5 | |
| 10a10 | |
| 6 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
8a5 - 2a5 = 6a5
On this circle, a line segment connecting point A to point D is called:
radius |
|
chord |
|
diameter |
|
circumference |
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).
If angle a = 64° and angle b = 41° what is the length of angle c?
| 111° | |
| 75° | |
| 110° | |
| 57° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 64° - 41° = 75°
The dimensions of this cube are height (h) = 5, length (l) = 1, and width (w) = 4. What is the volume?
| 20 | |
| 100 | |
| 18 | |
| 9 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 1 x 4
v = 20
