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.

Answer 1

A. C = 2 × π × r
C = 2 × 3.14 × 12
C = 75.36

Therefore, the correct formula is:

A. C = 2 × π × r
and the approximate circumference of a circle with a radius of 12 is 75.36.
