Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]
[tex]SA=2(3.14)(25)+942[/tex]
[tex]SA=157+942[/tex]
[tex]SA=1099
[/tex]
Therefore, the surface area of the cylinder is 1099 square inches.
