Question

I'm confused someone help

Answer 1

Lateral surface area of a cylinder is,


`l = 2\pi \ rh`

1st we need to calculate for the radius.


`r = (d)/(2) = (12)/(2) = 6`

The radius is always half of the diameter and in this case is 6.


`l \: = 2 * \pi * 6 * 20`


`l = 240\pi`


`l = 753.98224`

Lateral surface area is
≈ 753.98 or ≈ 754.
