To find the surface area of a cylinder, use the formula SA = 2(pi)(radius^2) + 2(pi)(radius)(height).
So now, plug in what you know.
SA = 2(3.14)(5^2) + 2(3.14)(5)(9)
SA = (6.28)(25) + (6.28)(45)
SA = 157 + 282.6
SA = 439.6 square cm
439.6 square cm is your surface area

Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem:
- The experiment was made 20 times.
- Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.
Then:

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
