🤓 Based on our data, we think this question is relevant for Professor McIntosh's class at ASU.

# Solution: A cylindrical rod formed from silicon is 16.8 cm long and has a mass of 2.17 kg. The density of silicon is 2.33 g/cm3. What is the diameter of the eylinder? (The volume of a eylinder is given by πr2h, where r is the radius, and h is its length.)
