A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The formula for the area of a circle is which of the following?
a = π d |
|
a = π r |
|
a = π r2 |
|
a = π d2 |
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.
The dimensions of this trapezoid are a = 5, b = 7, c = 7, d = 2, and h = 4. What is the area?
| 25\(\frac{1}{2}\) | |
| 32\(\frac{1}{2}\) | |
| 26 | |
| 18 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(7 + 2)(4)
a = ½(9)(4)
a = ½(36) = \( \frac{36}{2} \)
a = 18
If AD = 17 and BD = 8, AB = ?
| 9 | |
| 11 | |
| 6 | |
| 19 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDOrder the following types of angle from least number of degrees to most number of degrees.
right, acute, obtuse |

right, obtuse, acute |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
