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 pie to express your answer to the hundredths place.
A. 37.68
B. 452.16
C. 75.36
D. 18.84
C. 75.36
The correct formula to find the circumference of a circle with radius r is given by 2πr, where π (pi) is approximately 3.14.
Therefore, the approximate circumference of a circle with a radius of 12 would be 2 * 3.14 * 12 = 75.36.
