A cylindrical chimney with a diameter of 65 cm, a height of 18 m. How many square meters of tin is needed before its manufacture, only 10% is spent on riveting.
Since the pipe has the shape of a cylinder, we determine the area of the lateral surface of the cylinder.
We convert centimeters to meters, 65 cm = 0.65 m.
Side = 2 * n * R * h = n * D = n * 0.65 * 18 = n * 11.7 = 36.74 m2.
Determine the area of the sheet required for rivets.
Szak = Side * 0.1 = 3.674 m2.
Then S = Sbok + Szak = 36.74 + 3.674 = 40.414 m2.
Answer: You will need 40.414 m2 of tin.
