Question

Find the lateral area of a cylinder whose radius is 6 cm and height is 20 cm.

240 π cm 2
312 π cm 2
120 π cm 2

Answer 1

`240\pi cm^(2)`

Explanation:

Lateral area of a cylinder is the curved surface area, (which connects the top with the base)

Curved Surface Area=
`2\pi rh`

where r = radius of base

h = height of cylinder

Substituting the provided values:

Lateral area of cylinder =
`2\pi (6 cm)(20 cm)`

=
`240\pi cm^(2)`
