<h2><u>Question :-</u></h2>

Find the surface area of the cylinder.

<h3>___________________</h3>

<h2><u>Solution :-</u></h2>

<h3><u>Given Information :-</u></h3>

  • <u>Radius of the Cylinder ➢</u> 2 cm
  • <u>Height of the Cylinder ➢</u> 8 cm
  • <u>Value of π (pi) (not given) ➢</u> 3.14

<h3><u>To Find :-</u></h3>

  • Surface Area of the Cylinder

<h3><u>Formula Used :-</u></h3>

  • Area of cylinder = 2πr( r + h )

<h3><u>Calculation :-</u></h3>

<em><u>Substituting the values given in the formula, We get, </u></em>

⇒ Area of Cylinder = 2 × 3.14 × 2 ( 2 + 8 )

⇒ Area of cylinder = 2 × 3.14 × 2 ( 10 )

⇒ Area of cylinder = 2 × 3.14 × 20

<em><u>Calculating further, We get, </u></em>

⇒ Area of cylinder = 125.66 cm²

<h3>___________________</h3>

<h2><u>Final Answer :-</u> </h2>

  • Area of cylinder = 125.66 cm²
