The dimensions of this cube are height (h) = 8, length (l) = 5, and width (w) = 5. What is the volume?
| 200 | |
| 84 | |
| 16 | |
| 40 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 5 x 5
v = 200

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If angle a = 27° and angle b = 43° what is the length of angle c?
| 90° | |
| 111° | |
| 107° | |
| 110° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 27° - 43° = 110°
Which of the following statements about a triangle is not true?
exterior angle = sum of two adjacent interior angles |
|
sum of interior angles = 180° |
|
perimeter = sum of side lengths |
|
area = ½bh |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
What is the circumference of a circle with a diameter of 10?
| 26π | |
| 10π | |
| 4π | |
| 1π |
The formula for circumference is circle diameter x π:
c = πd
c = 10π
