Question

Find the circumference of the circle below. (Use 3.14 for Pi)

A. 78.5 cm
B. 15.7 cm
C. 31.4 cm
D. 314 cm

Answer 1

C. 31.4 cm

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

Answer 2

so the right answer is 31.4 cm(option C)
