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

Answer:
B = 2xy
Step-by-step explanation:
pretty sure this is it
Hence, the required inequality is x+y≤4, 7x+4y≤1150
<h2>What is inequality?</h2>
inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
<h3>How to solve?</h3>
Let x be the number of adults and y be the number of campers.
There are rooms for 450 people, so
x+y≤450.
Each adult costs $7, then x adults cost $7x.
Each camper costs $4, then y campers cost $4y.
There is a maximum budget of $1,150, so
7x+4y≤1,150
Hence, you get the system of two inequalities:
x+y≤4
7x+4y≤1150
