The dimensions of this cylinder are height (h) = 9 and radius (r) = 2. What is the volume?
| 36π | |
| 252π | |
| 4π | |
| 648π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(22 x 9)
v = 36π
On this circle, a line segment connecting point A to point D is called:
diameter |
|
radius |
|
chord |
|
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).
On this circle, line segment CD is the:

radius |
|
chord |

What is the circumference of a circle with a radius of 11?
| 30π | |
| 11π | |
| 4π | |
| 22π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 11)
c = 22π
