Answer:
C. 31.4 cm
Step-by-step explanation:
→The formula for finding the circumference of a circle is:
C = 2πr
→However, it states that we use 3.14 for π:
C = 2(3.14)r
→The "r," is the radius, which is a straight line from the perimeter to the center. In this case, it is already given to us as 5 cm.
C = 2(3.14)(5)
C = 31.4
