[tex]\blue\textsf{\textbf{\underline{\underline{Question:-}}}}[/tex]
What is the surface area of the cylinder with height 2 yd and radius 7 yd?
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and how to Solve:-}}}}[/tex]
[tex]\textsf{Formula for Surface Area (SA) of a Cylinder:-}[/tex]
[tex]\dashrightarrow\bigstar{\boxed{\bf{A=2\pi rh+2\pi r^2}}}\dashleftarrow[/tex]
Where
[tex]\bold{A=Area}[/tex]
[tex]\bf{\pi =pi (3.14...)}[/tex]
[tex]\bold{r=radius}[/tex]
[tex]\bold{h=height}[/tex]
Given:-
[tex]\bold{r=7}[/tex]
[tex]\bold{h=2}[/tex]
Solving for S.A.:-
[tex]\bold{SA=2\pi (7)(2)+2\pi (7)^2}[/tex]
[tex]\bold{SA=2\pi (14)+2\pi (49)}[/tex]
On further simplification,
[tex]\bold{SA=28\pi +98\pi }[/tex]
[tex]\bold{SA=126\pi }[/tex]
And finally,
[tex]\dashrightarrow\bigstar\boxed{\bold{SA=395.841\:yd}}\dashleftarrow[/tex]
Good luck.
