What is the average outside diameter of a cylinder with a taped circumference of 9,425mm?

To determine the average outside diameter of a cylinder from its circumference, you can use the relationship between circumference (C) and diameter (D), given by the formula:

[ C = \pi \times D ]

In this case, we have the circumference of the cylinder as 9,425 mm. To find the diameter, rearrange the formula to solve for D:

[ D = \frac{C}{\pi} ]

Substituting the circumference into the equation gives:

[ D = \frac{9,425 \text{ mm}}{\pi} ]

Using the value of π (approximately 3.14159):

[ D \approx \frac{9,425 \text{ mm}}{3.14159} \approx 2995.4 \text{ mm} ]

Rounding this value to the nearest hundred gives an approximate outside diameter of 3,000 mm. Therefore, this corresponds to the choice that indicates 3,000 mm as the average outside diameter.

Understanding this calculation is crucial for accurately determining dimensions in welding and fabrication, where measurements must be precise to ensure proper fit and quality in constructions.
