Answer:

AL=2πrh

Step-by-step explanation:

The expression for the lateral area of a cylinder is given as

AL=2πrh

where r is the radius of the circular surface of the cylinder

and h represents the height of the cylinder

while the constant π has a value of 3.142

Now upon substitution we can solve for the lateral area and the unit for the lateral area is (units)^2 i,e cm^2, mm^2 or m^2 etc.
