1

The dimensions of this cylinder are height (h) = 6 and radius (r) = 8. What is the surface area?

48% Answer Correctly
66π
104π
224π
8π
Solution

The surface area of a cylinder is 2πr2 + 2πrh:

sa = 2πr2 + 2πrh
sa = 2π(82) + 2π(8 x 6)
sa = 2π(64) + 2π(48)
sa = (2 x 64)π + (2 x 48)π
sa = 128π + 96π
sa = 224π

2

The endpoints of this line segment are at (-2, 0) and (2, 2). What is the slope of this line?

46% Answer Correctly
\(\frac{1}{2}\)
-3
-1\(\frac{1}{2}\)
-1
Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 0) and (2, 2) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(2.0) - (0.0)}{(2) - (-2)} \) = \( \frac{2}{4} \)
m = \(\frac{1}{2}\)

3

Which types of triangles will always have at least two sides of equal length?

54% Answer Correctly

equilateral, isosceles and right

equilateral and right

isosceles and right

equilateral and isosceles
Solution

An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.

4

If the base of this triangle is 8 and the height is 7, what is the area?

58% Answer Correctly
28
60
27
91
Solution

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 8 x 7 = \( \frac{56}{2} \) = 28

5

To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

84% Answer Correctly

Inside

First

Last

Odd
Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
