Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 12? Use 3.14 for π and express your answer to the hundredths place.
75.36
18.84
37.68
452.16
The correct formula to find the approximate circumference of a circle is C = 2πr, where r is the radius of the circle.
Substituting the given values:
C = 2 x 3.14 x 12
C ≈ 75.36
Therefore, the answer is 75.36.
