Order of Operations:

To simplify the expression follow the order of operations: (PEMDAS)

1. Evaluate the expressions inside the Parenthesis/Brackets (P).

2. Evaluate Powers/Exponents (E).

3. Multiply and/or Divide in order from left to right (MD).

4. Add and/or Subtract in order from left to right (AS).

A simple technique for remembering the order of operations is turned

into phrase "Please Excuse My Dear Aunty Sally"

$\"\"$

Volume of the cone is $\"\"$ .

Where r is the radius and h is the height of the cone respectively.

$\"\"$ $\"\"$

$\"\"$ (Substitute: r = 3x, c = $\"\"$ )

First operation is evaluating powers.

$\"\"$ (Evaluate the power: $\"\"$ ) $\"\"$

Next operation is multiplication.

$\"\"$ (Multiply: $\"\"$ )

$\"\"$ (Divide: $\"\"$ ) $\"\"$

The volume of the cone is $\"\"$ .
