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⋅150

C≈2⋅3.14⋅450

C≈3.14⋅450^2

C≈3.14⋅450÷2

Please answer this correctly. Thank you.

C≈2⋅3.14⋅450

To find the approximate circumference of a circle with a given radius, we use the formula:

C = 2 * π * r

where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Out of the four options provided, the correct formula to find the approximate circumference of a circle with a radius of 450 is:

C ≈ 2 * 3.14 * 450

So, the correct option is:

C ≈ 2 * 3.14 * 450

The correct formula to find the approximate circumference of a circle is C≈2⋅3.14⋅radius. Therefore, in this case, the correct formula to find the approximate circumference of a circle with a radius of 450 is C≈2⋅3.14⋅450 (option B).
