Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression:

2π(6,400 + 450) ÷ 120 × 60

1. First, perform the addition inside the parentheses:

6,400 + 450 = 6,850

So the expression becomes:

2π(6,850) ÷ 120 × 60

2. Next, multiply 2π by 6,850:

2π * 6,850 ≈ 43,004.12 (rounded to two decimal places)

So the expression becomes:

43,004.12 ÷ 120 × 60

3. Now, perform the division:

43,004.12 ÷ 120 ≈ 358.3685 (rounded to four decimal places)

So the expression becomes:

358.3685 × 60

4. Finally, perform the multiplication:

358.3685 × 60 ≈ 21,502.11 (rounded to two decimal places)

So the final result is approximately 21,502.11.
