To calculate the circumference of a circle, we can use the formula C = π * d, where C represents the circumference and d represents the diameter.
Given that the diameter is 20, we can use the formula to find the circumference:
C = 3.14 * 20
C ≈ 62.8 (rounded to the tenths place)
Therefore, the approximate circumference of the circle is 62.8 units.
What is the approximate circumference of a circle that has a diameter of 20? Use 3.14 for pi and express your answer in the tenths place
