Given:

Height of cylinder = 12 cm

Diameter of cylinder = 6 cm

To find:

Surface area of the cylinder

Solution:

Radius = 6 ÷ 2 = 3 cm

Surface area formula:

SA=2\pi r^2+2 \pi rh

Substitute the given values.

SA=2\times3.14 \times3^2+2\times3.14 \times3  \times12

     =56.52+226.08

     = 286.2 cm²

The surface area of the cylinder is 286.2 cm².
