which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 450

Answer 1

The correct formula to find the approximate circumference of a circle with a radius of 450 is:

C = 2πr

where C is the circumference and r is the radius.

To get the approximate answer, you can use the approximation for π which is 3.14.

So the formula becomes:

C ≈ 2 x 3.14 x 450

C ≈ 2826

Therefore, the approximate circumference of the circle is 2826 units.
