Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 450?
C ≈ 3.14 ⋅ 450 ÷ 2
C ≈ 2⋅3.14 ⋅ 450
C ≈ 3.14 ⋅450 * 2
C ≈ 3.14 ⋅ 150
The correct formula for finding the approximate circumference of a circle that has a radius of 450 is:
C ≈ 2πr, where r is the radius and π (pi) is approximately 3.14.
Therefore, the answer is:
C ≈ 2 x 3.14 x 450
The correct answer is: C ≈ 2 x 3.14 x 450, which simplifies to C ≈ 2,826.
