Where r is the radius of the cylinder and h is the height of the cylinder.
AnnyKZ [126]
<h3>Given:-</h3>
  • radius = 7 inches
  • height = 9 inches

\\  \\

<h3>To find:</h3>
  • Surface area of cylinder

\\  \\

we know:-

\bigstar \boxed{ \rm Surface \: Area \: of \: Cylinder=2\pi rh+2\pi {r}^{2} }

\\  \\

So:-

⇢SA of cylinder=2πrh+2πr²

\\

⇢SA of cylinder = 2πr(h+r)

\\

⇢SA of cylinder = 2 × π × 7(7 + 9)

\\

⇢SA of cylinder = 2 × π × 7 (16)

\\

⇢SA of cylinder = 2 × π × 112

\\

⇢SA of cylinder = 2 × 112 × π

\\

⇢SA of cylinder = 224π inches ²

\\
