can somebody help me on this

Answer:
48π square units
Step-by-step explanation:
The lateral surface area of a cylinder is = 2 π r h.
Where h = 6, r = 4 (from the figure)
Then the lateral surface area is: 2*6*4*π = 48π square units
For this case we have that by definition, the lateral area of a cylinder is given by:
[tex]A_ {l} = 2 * \pi * r * h[/tex]
Where:
A: It is the radius of the cylinder
h: It's the height
[tex]r = 4 \ units\\h = 6 \ units[/tex]
Substituting we have:
[tex]A_ {l} = 2 * \pi * 4 * 6\\A_ {l} = 48 \pi \ units ^ 2[/tex]
Answer:
[tex]48 \pi \ units ^ 2[/tex]
