Answer:

64π square units

Explanation:

the formula for finding the lateral surface area of a cylinder is 2πrh

so if you substitute the variables with the numbers, you get,

2π8*4=64π

Answer:
$64\pi\ units^2$ or
$201.06\ units^2$

Explanation:

The formula that is used to calculate the Lateral surface area (LSA) of a cylinder is:

$LSA=2\pi rh$

Being the radius of the cylinder r and the height of the cylinder h.

Knowing tha radius 8 units and the height 4 units, you can substitute values into the formula
$LSA=2\pi rh$ .

Therefore, the Lateral surface area of the cylinder with radius 8 and height 4 is:

$LSA=2\pi (8units)(4units)$

$LSA=64\pi\ units^2=201.06\ units^2$
