Question

Label the net for the cylinder. Then find the surface area of the cylinder. Give your answer in term of π and as a decimal number rounded to the nearest tenth.

Answer 1

π=3.14 or 22/7

Explanation:

Answer 2

(a)

`r = 7ft`

`h = 5ft`

(b)

`SA = 168\pi`

`SA = 528.0`

Explanation:

Given

See attachment for complete question

Solving (a) Label all parts

From the attachment, the known part of the cylinder are its radius and its height.

The values are:

`r = 7ft`

`h = 5ft`

Solving (b): The surface area

This is calculated as:

`SA = 2\pi r(r + h)`

So, we have:

`SA = 2\pi *7*(7 + 5)`

`SA = 2\pi *7*12`

`SA = 168\pi`

As a decimal, we have:

`SA = 168 * (22)/(7)`

`SA = 528.0`
