The dimensions of this cylinder are height (h) = 1 and radius (r) = 9. What is the volume?
| 81π | |
| 75π | |
| 448π | |
| 175π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(92 x 1)
v = 81π
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).

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
Solve for b:
b - 2 < \( \frac{b}{-2} \)
| b < 2\(\frac{7}{9}\) | |
| b < 1\(\frac{1}{3}\) | |
| b < -\(\frac{5}{17}\) | |
| b < -\(\frac{16}{31}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
b - 2 < \( \frac{b}{-2} \)
-2 x (b - 2) < b
(-2 x b) + (-2 x -2) < b
-2b + 4 < b
-2b + 4 - b < 0
-2b - b < -4
-3b < -4
b < \( \frac{-4}{-3} \)
b < 1\(\frac{1}{3}\)
If the length of AB equals the length of BD, point B __________ this line segment.

midpoints |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
