The dimensions of this cube are height (h) = 1, length (l) = 8, and width (w) = 8. What is the volume?
| 324 | |
| 216 | |
| 54 | |
| 64 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 8 x 8
v = 64
Which of the following is not true about both rectangles and squares?
the lengths of all sides are equal |
|
the area is length x width |
|
all interior angles are right angles |
|
the perimeter is the sum of the lengths of all four sides |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
What is the area of a circle with a radius of 5?
| 4π | |
| 81π | |
| 7π | |
| 25π |
The formula for area is πr2:
a = πr2
a = π(52)
a = 25π
Which of the following statements about a parallelogram is not true?
a parallelogram is a quadrilateral |
|
the area of a parallelogram is base x height |
|
opposite sides and adjacent angles are equal |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
