The wall thickness of a hollow cylinder is 5 mm and its inner diameter is 3 cm. What is the outer diameter of the cylinder?
To find the outer diameter of the taken hollow cylinder, we will use the formula: D = d + 2S.
Values of variables: d – inner diameter of the cylinder (d = 3 cm = 30 mm); S – wall thickness (S = 5 mm).
Let’s perform the calculation: D = d + 2S = 30 + 2 * 5 = 40 mm.
Answer The outer diameter of the taken hollow cylinder is 40 mm.
