Solution:-

• 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.

• Taking value of π = 3.14

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 4245.28 cm². [Answer]

Step-by-step explanation:

Solution:

• 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. Taking value of π = 3.14

Hence, Surface area of the cylinder = 2 x 3.14 ×

13(13 +39)

Surface area of the cylinder = (81.64 x 52) cm²

Surface area of the cylinder = 4245.28 cm²

The surface area of the cylinder is 4245.28 cm².
