There are 52 weeks in one year and Flora records her pet hamsters weight once every week for one year, so she recored 52 weight observations.

Most questions on Brainly offer 5 points in return for answering one question,
but here you've listed five of them to be answered for 5 points. That's kind of
much.
Also, it's not clear what cylinders Question-2 and Questioin-3 refer to.
They might be the two pictures under the question, but we don't rally know.
Fortunately, all five of your questions are answered with the same formula ...
the formula for the volume of a cylinder.
Here it is:
Volume of a cylinder = ( π ) · (radius)² · (height or length) .
V = π R² H .
That's it. That's all you need to answer any or all of the five questions.
So I've actually given you everything you need to answer them, and in
doing that, I've already earned 5 points. But, being the ever helpful guy
that I am, I'll work out two of the questions for you, to show you how to
use the formula.
Question #1). <span>A cylinder has a radius of 14 m and a height of 6 m.
</span>Volume = π R² H
= (π) (14m)² (6m)
= (π) (196m²) (6m)
= 1,176 π m³ = 71,763,930 π in³
(Notice how confusingly and sloppily the question is written . . .
the dimensions of the cylinder are given in meters, but the
answer choices are listed in cubic-inches. I've shown the
answer in both units.)
Question 5). <span>A can has a radius of 2.8 feet and holds 86.21 cubic feet.
</span><span>Volume = π R² H
86.2 ft³ = π (2.8 ft)² (Height)
86.2 ft³ = π (7.84 ft²) (Height)
Height = (86.2 ft³) / (7.84 π ft²)
= 3.5 ft
</span>
I think 3.323 units would be the correct answer. Are you asking what the length of a single side is?
Answer:
the correct answer is the third one. (1, 16), (2, 20), (3, 24)
Step-by-step explanation:
A perimeter is a path that surrounds a two-dimensional shape.
In the first case, 1 rectangle, the perimeter is the sum of all the sides:
Perimeter = 6 + 2 + 6 + 2 = 16
In the second case, 2 rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 6 + 2 + 2 = 20
In the third case, three rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 2 + 6 + 2 + 2 + 2 = 24
In none of the cases, you take into consideration the interal sides. Just the external sides, so the correct answer is the third one.
