Which of the following is not a part of PEMDAS, the acronym for math order of operations?
exponents |
|
addition |
|
pairs |

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.)
What is the circumference of a circle with a radius of 15?
| 19π | |
| 16π | |
| 10π | |
| 30π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 15)
c = 30π
