The dimensions of this cylinder are height (h) = 7 and radius (r) = 9. What is the volume?
| 648π | |
| 567π | |
| 9π | |
| 216π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(92 x 7)
v = 567π

On this circle, line segment CD is the:
circumference |
|
chord |
|
diameter |
|
radius |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
exponents |
|
pairs |
|
addition |
|
division |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
If a = c = 9, b = d = 4, what is the area of this rectangle?
| 1 | |
| 36 | |
| 2 | |
| 49 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 9 x 4
a = 36
