In this case, supervised learning would be more appropriate. Supervised learning algorithms work by training a model on labeled data, where the outcome (e.g., whether a disease outbreak occurred) is known. This allows the model to learn patterns from the medical records that can predict future outbreaks or help allocate resources effectively. Unsupervised learning, on the other hand, would be useful for clustering or anomaly detection tasks but may not provide direct predictions based on labeled outcomes like supervised learning can.
On the day of her examination, Riya sharpened her pencil from both ends as shown below. 
The diameter of the cylindrical and conical part of the pencil is 4.2 mm. If the height of each conical part is 2.8 mm and the length of the entire pencil is 105.6 mm, find the total surface area of the pencil.
