The dimensions of this cylinder are height (h) = 3 and radius (r) = 7. What is the volume?
| 45π | |
| 32π | |
| 147π | |
| 252π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 3)
v = 147π
Which of the following expressions contains exactly two terms?
monomial |
|
binomial |
|
polynomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
What is the circumference of a circle with a radius of 10?
| 7π | |
| 16π | |
| 20π | |
| 5π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 10)
c = 20π
If the base of this triangle is 8 and the height is 7, what is the area?
| 97\(\frac{1}{2}\) | |
| 28 | |
| 45 | |
| 91 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 8 x 7 = \( \frac{56}{2} \) = 28
