If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
bisects |
|
midpoints |
|
trisects |
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.
On this circle, a line segment connecting point A to point D is called:
diameter |
|
chord |
|
radius |
|
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).
What is the area of a circle with a radius of 3?
| 9π | |
| 49π | |
| 81π | |
| 16π |
The formula for area is πr2:
a = πr2
a = π(32)
a = 9π
The dimensions of this cube are height (h) = 1, length (l) = 6, and width (w) = 8. What is the surface area?
| 348 | |
| 124 | |
| 38 | |
| 108 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 6 x 8) + (2 x 8 x 1) + (2 x 6 x 1)
sa = (96) + (16) + (12)
sa = 124
A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
equal angle |
|
parallel |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
