1

A cylinder with a radius (r) and a height (h) has a surface area of:

53% Answer Correctly

π r2h

2(π r2) + 2π rh

4π r2

π r2h2
Solution

A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.

2

Which of the following statements about math operations is incorrect?

70% Answer Correctly

you can add monomials that have the same variable and the same exponent

all of these statements are correct

you can subtract monomials that have the same variable and the same exponent

you can multiply monomials that have different variables and different exponents
Solution

You can only add or subtract monomials that have the same variable and the same exponent. For example, 2a + 4a = 6a and 4a2 - a2 = 3a2 but 2a + 4b and 7a - 3b cannot be combined. However, you can multiply and divide monomials with unlike terms. For example, 2a x 6b = 12ab.

3

A coordinate grid is composed of which of the following?

89% Answer Correctly

x-axis

origin

y-axis

all of these
Solution

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.

4

Simplify 8a x 6b.

86% Answer Correctly
14ab
48\( \frac{b}{a} \)
48ab
48a2b2
Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

8a x 6b = (8 x 6) (a x b) = 48ab

5

If a = 6, b = 6, c = 6, and d = 1, what is the perimeter of this quadrilateral?

88% Answer Correctly
26
19
28
23
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 6 + 6 + 6 + 1
p = 19
