Find the surface area of a cylinder
whose radius is 5 cm and whose
height is 10 cm.
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
Radius of a cylinder (r) is 5 cm
Height of a cylinder (h) is 10 cm
<h3>To Find:-</h3>
The surface area of a cylinder
<h2>Solution:-</h2>
We know the formula of surface area of a cylinder is –
<h2>

</h2>
So, putting the value of r = 5 cm and h = 10 cm we get,
2πr(r + h) = 2 ×
× 5(5 + 10)
=
(5 + 10)
=
× 15
= 
= 
= 471.43 cm²
