The formula for the circumference of a circle is C = π*d, where d is the diameter.
Given diameter = 20, we can calculate the circumference using π = 3.14:
C = 3.14 * 20 = 62.8
Therefore, the approximate circumference of the circle is 62.8.
What is the approximate circumference of a circle that has a diameter of 20? Use 3.14 for π and express your answer to the tenths place.
