On this circle, line segment AB is the:
diameter |
|
circumference |
|
chord |
|
radius |
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).
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles |
|
isosceles and right |
|
equilateral, isosceles and right |
|
equilateral and right |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
What is the area of a circle with a diameter of 4?
| 9π | |
| 25π | |
| 6π | |
| 4π |
The formula for area is πr2. Radius is circle \( \frac{diameter}{2} \):
r = \( \frac{d}{2} \)
r = \( \frac{4}{2} \)
r = 2
a = πr2
a = π(22)
a = 4π
If the base of this triangle is 7 and the height is 4, what is the area?
| 35 | |
| 52\(\frac{1}{2}\) | |
| 14 | |
| 36 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 4 = \( \frac{28}{2} \) = 14
