The total surface area of a cylinder is given by the formula

Given diameter, d=12meters, we will solve for radius

The height is given as 9meters
Substituting for r and h in the formula will give


Hence the surface area of the cylinder is 565.2m²
Answer:
15
Step-by-step explanation:

Would this be the correct answer? If not, can you further explain the question?(11x+8y)(11x-8y)
11/4 is the mixed fraction of that
Let's look at each one of the intervals.
Interval A
Interval A looks like she's going at a pretty steady pace, so Interval A is not the correct answer.
Interval B
Interval B looks like she stays at 2.5 for an hour. That looks like a traffic jam to me!
The correct answer is Interval B.
