Solution
The diameter of a circle can be calculated using the formula: Diameter = Circumference/π
Question 1: Given the circumference is 18.84 cm, the diameter would be: Diameter = 18.84 cm / π = 5.99 cm (rounded to 2 decimal places)
Question 2: Given the circumference is 64.81 cm, the diameter would be: Diameter = 64.81 cm / π = 20.63 cm (rounded to 2 decimal places)
Question 3: Given the circumference is 74.62 mm, the diameter would be: Diameter = 74.62 mm / π = 23.75 mm (rounded to 2 decimal places)
