Find the lateral surface area of this

Ksenya-84 [330]

Answer:

$A=157.07\ cm^2$

Step-by-step explanation:

Given that,

The radius of a cylinder, r = 5 cm

Height of the cylinder, h = 5 cm

We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of the cylinder is given by :

$A=2\pi r h$

Put all the values,

$A=2\pi\times 5\times 5\\\\=157.07\ cm^2$

So, the lateral surface area of the cylinder is $157.07\ cm^2$ .
