1) The circumference is calculated by the formula l = 2пr.
Since the diameter of the circle is D = 2r, then l = пD.
Hence D = l / n. Where l is the length of the circle, n = 3.14 and D is the diameter of the circle.
D = 20: 3.14 = 6.369 cm
2) Round up to hundredths of 6.37 cm
Answer: diameter 6.37 cm.
