A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The dimensions of this cylinder are height (h) = 1 and radius (r) = 3. What is the volume?
| 98π | |
| 9π | |
| 4π | |
| 256π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(32 x 1)
v = 9π
Solve for c:
-4c - 7 = 7 + 8c
| \(\frac{5}{6}\) | |
| \(\frac{3}{5}\) | |
| -\(\frac{4}{9}\) | |
| -1\(\frac{1}{6}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
-4c - 7 = 7 + 8c
-4c = 7 + 8c + 7
-4c - 8c = 7 + 7
-12c = 14
c = \( \frac{14}{-12} \)
c = -1\(\frac{1}{6}\)
A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
parallel |
|
right angle |
|
equal angle |
A trapezoid is a quadrilateral with one set of parallel sides.
For this diagram, the Pythagorean theorem states that b2 = ?
c2 + a2 |
|
c - a |
|
c2 - a2 |
|
a2 - c2 |
The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)
