$\blue\textsf{\textbf{\underline{\underline{Question:-}}}}$

What is the surface area of the cylinder with height 2 yd and radius 7 yd?

$\blue\textsf{\textbf{\underline{\underline{Answer and how to Solve:-}}}}$

$\textsf{Formula for Surface Area (SA) of a Cylinder:-}$

$\dashrightarrow\bigstar{\boxed{\bf{A=2\pi rh+2\pi r^2}}}\dashleftarrow$

Where

$\bold{A=Area}$

$\bf{\pi =pi (3.14...)}$

$\bold{r=radius}$

$\bold{h=height}$

Given:-

$\bold{r=7}$

$\bold{h=2}$

Solving for S.A.:-

$\bold{SA=2\pi (7)(2)+2\pi (7)^2}$

$\bold{SA=2\pi (14)+2\pi (49)}$

On further simplification,

$\bold{SA=28\pi +98\pi }$

$\bold{SA=126\pi }$

And finally,

$\dashrightarrow\bigstar\boxed{\bold{SA=395.841\:yd}}\dashleftarrow$
