CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. The label covers the curved surface: 2πrh2\pi r h.

  2. = 2×227×14×10=8802 \times \frac{22}{7} \times 14 \times 10 = 880 cm².

Worth noting

1,496 cm² adds one circular end and 2,112 cm² adds both ends; a label covers only the curved side. 6,160 is the volume in cm³.
