A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
parallel |
|
right angle |
|
equal length |
A trapezoid is a quadrilateral with one set of parallel sides.
Order the following types of angle from least number of degrees to most number of degrees.
acute, right, obtuse |
|
acute, obtuse, right |
|
right, obtuse, acute |
|
right, acute, obtuse |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
What is the area of a circle with a diameter of 8?
| 2π | |
| 25π | |
| 16π | |
| 4π |
The formula for area is πr2. Radius is circle \( \frac{diameter}{2} \):
r = \( \frac{d}{2} \)
r = \( \frac{8}{2} \)
r = 4
a = πr2
a = π(42)
a = 16π
The dimensions of this cube are height (h) = 4, length (l) = 4, and width (w) = 4. What is the surface area?
| 228 | |
| 70 | |
| 96 | |
| 264 |
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 4 x 4) + (2 x 4 x 4) + (2 x 4 x 4)
sa = (32) + (32) + (32)
sa = 96
