A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The formula for the area of a circle is which of the following?
a = π r |
|
a = π d2 |
|
a = π d |
|
a = π r2 |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
If the base of this triangle is 6 and the height is 1, what is the area?
| 90 | |
| 21 | |
| 49\(\frac{1}{2}\) | |
| 3 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 6 x 1 = \( \frac{6}{2} \) = 3
If angle a = 64° and angle b = 70° what is the length of angle c?
| 46° | |
| 67° | |
| 83° | |
| 110° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 64° - 70° = 46°
Which of the following expressions contains exactly two terms?
polynomial |
|
binomial |
|
monomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
