.
<u>Step-by-step explanation:</u>
We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.
We know that the formula of the lateral area of a cylinder is given by:
Lateral area of cylinder = 
Substituting the given values in the formula to get:
Lateral Area =
= 153
Let's start with option A --> $23 per hour x 40 hours = 23 x 40 = 920 = $920
That means we have to find how many $ x 5% = $920
We'll call our unknown amount: "B", so B x 0.05 = $920
To find B you have to get ride of everything on its side:
(B x 0.05) / 0.05 = 920 / 0.05 ----> we have to do the same operations on each side.
Now we have B = 920 / 0.05 ----> B = $18,400
The salesperson must sell $18,400 in order to earn the same amount as the first option.
