Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
a parallelogram is a quadrilateral |
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).
If a = 7, b = 3, c = 3, and d = 9, what is the perimeter of this quadrilateral?
| 18 | |
| 19 | |
| 22 | |
| 20 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 7 + 3 + 3 + 9
p = 22
The dimensions of this cylinder are height (h) = 1 and radius (r) = 4. What is the surface area?
| 192π | |
| 24π | |
| 40π | |
| 180π |
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(42) + 2π(4 x 1)
sa = 2π(16) + 2π(4)
sa = (2 x 16)π + (2 x 4)π
sa = 32π + 8π
sa = 40π
