What is the circumference of a circle with a radius of 5?
| 32π | |
| 10π | |
| 12π | |
| 16π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 5)
c = 10π
The dimensions of this cube are height (h) = 3, length (l) = 9, and width (w) = 9. What is the volume?
| 243 | |
| 48 | |
| 30 | |
| 18 |
The volume of a cube is height x length x width:
v = h x l x w
v = 3 x 9 x 9
v = 243
If BD = 9 and AD = 18, AB = ?
| 4 | |
| 12 | |
| 5 | |
| 9 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhich of the following is not a part of PEMDAS, the acronym for math order of operations?
division |
|
pairs |
|
addition |
|
exponents |
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 = 5, b = 1, c = 8, and d = 8, what is the perimeter of this quadrilateral?
| 12 | |
| 16 | |
| 22 | |
| 17 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 5 + 1 + 8 + 8
p = 22
