Question

Can somebody help me on this

Answer 1

For this case we have that by definition, the lateral area of a cylinder is given by:

`A_ {l} = 2 * \pi * r * h`

Where:

A: It is the radius of the cylinder

h: It's the height

`r = 4 \ units\\h = 6 \ units`

Substituting we have:

`A_ {l} = 2 * \pi * 4 * 6\\A_ {l} = 48 \pi \ units ^ 2`

Answer:

`48 \pi \ units ^ 2`

Option B

Answer 2

48π square units

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
