<h2><u>Solution</u>:-</h2>
• Surface area of a cylinder = 2πr(r + h) sq. units.
In the above diagram,
Radius (r) of the cylinder = 13 cm.
Height (h) of the cylinder = 39 cm.
<h3>• Taking value of π = 3.14</h3>
Hence, Surface area of the cylinder = 2 × 3.14 × 13(13 + 39)
Surface area of the cylinder = (81.64 × 52) cm²
Surface area of the cylinder = 4245.28 cm²
The surface area of the cylinder is <u>4</u><u>2</u><u>4</u><u>5</u><u>.</u><u>2</u><u>8</u><u> </u><u>cm²</u>. [Answer]
