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