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:
[tex]SA=2\pi r^2+2 \pi rh[/tex]
Substitute the given values.
[tex]SA=2\times3.14 \times3^2+2\times3.14 \times3 \times12[/tex]
[tex]=56.52+226.08[/tex]
= 286.2 cm²
The surface area of the cylinder is 286.2 cm².
