Answer:
The height of cylinder is: h = 80.07 cm
The diameter of cylinder is: d = 3.5 cm
Step-by-step explanation:
Curved surface area of cylinder = 880 cm^2
Volume of cylinder = 770 cm^3
We need to find its diameter and height.
The formula used are:
If we divide volume by curved surface, we can find radius
So, we get radius r = 1.75
Now, we can find height using curve surface area formula:
So, the height of cylinder is: h=80.07 cm
Now finding diameter using formula:
Putting value of r in above formula:
So, the diameter of cylinder is: d = 3.5 cm

The correct answer is:
Option A: A 10x — 15000 ≥ 50000
Step-by-step explanation:
Given that the total cost of manufacturing by the company is $15000.
Let x be the number of gallons the company sells.
It is also mentioned that the company earns $10 on each gallon.
So the total profit will be the the difference of the selling cost of gallons and manufacturing cost
Mathematically,
Now it is mentioned that the profit should be at least 50000 dollars which means the profit can be minimally 50000 and also can be greater than it so
The number of gallons can be found by solving the obtained inequality.
Hence,
The correct answer is:
Option A: A 10x — 15000 ≥ 50000
