Answer:

(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
