The dimensions of this cylinder are height (h) = 5 and radius (r) = 5. What is the volume?
| 320π | |
| 512π | |
| 6π | |
| 125π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(52 x 5)
v = 125π
A(n) __________ is to a parallelogram as a square is to a rectangle.
triangle |
|
quadrilateral |
|
trapezoid |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
The dimensions of this cube are height (h) = 1, length (l) = 2, and width (w) = 6. What is the volume?
| 12 | |
| 162 | |
| 20 | |
| 75 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 2 x 6
v = 12
What is 6a + 5a?
| 30a | |
| 11 | |
| 11a | |
| a2 |
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.
6a + 5a = 11a
On this circle, a line segment connecting point A to point D is called:
chord |
|
circumference |
|
diameter |
|
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).
