The dimensions of this cylinder are height (h) = 9 and radius (r) = 8. What is the volume?
| 576π | |
| 320π | |
| 128π | |
| 25π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(82 x 9)
v = 576π
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
normalizing |
|
squaring |
|
deconstructing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The formula for the area of a circle is which of the following?
c = π r |
|
c = π d |
|
c = π d2 |
|
c = π r2 |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
A trapezoid is a quadrilateral with one set of __________ sides.
parallel |
|
right angle |
|
equal length |
|
equal angle |
A trapezoid is a quadrilateral with one set of parallel sides.
On this circle, line segment CD is the:
chord |
|
radius |
|
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).
