binomial |
|
monomial |
|
polynomial |
|

On this circle, line segment CD is the:
circumference |
|
diameter |
|
radius |
|
chord |
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).
If side x = 12cm, side y = 11cm, and side z = 6cm what is the perimeter of this triangle?
| 26cm | |
| 29cm | |
| 40cm | |
| 36cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 11cm + 6cm = 29cm
If AD = 14 and BD = 12, AB = ?
| 14 | |
| 3 | |
| 2 | |
| 15 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhat is the circumference of a circle with a diameter of 18?
| 28π | |
| 18π | |
| 17π | |
| 30π |
The formula for circumference is circle diameter x π:
c = πd
c = 18π
