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.
1. 75.36
2. 37.68
3. 18.84
4. 452.16
4. 452.16
The correct formula to find the circumference of a circle is: C = 2πr
Plugging in the values: C = 2 * 3.14 * 12 = 75.36
So the correct answer is 75.36.
