The dimensions of the cylinder can be used to minimise cost of manufacture.
<h3>How to we find minimised cost?</h3>
Let's ignore the metal's thickness and assume that the material cost to manufacture is precisely proportionate to the surface area of a perfect cylinder.
A=2πr(r+h)
Given that V=1000=r2h and h=1000=r2, we can write
A=2πr(r+1000πr2)
A=2πr2+2000r−1
By setting the derivative to zero, we may determine the value of r that minimises A:
A′=4πr−2000r−2
0=4πr−2000r−2
2000r−2=4πr
2000=4πr3
r=500π−−−√3
r=5.419 + cm
h=1000πr2=10.838 + cm
The can with the smallest surface area has a volume of 1000 cm 3 and measures 5.419+ cm in radius and 10.838+ cm in height. The can has a surface area of 553.58 cm 2. Given a constant volume, the cylinder with diameter equal to height has the least surface area.
Can surface area (cm2) versus. radius (cm), where capacity = 1000cm 3.

Answer:
Explanation:
ABSTRACT. Without a massive survey of U.S. employers, it is impossible to estimate or describe the full spectrum of those who provide occupational safety and health (OSH) services to the U.S. workforce. However, it was possible to assemble a description of the four traditional or core OSH professions (occupational safety, industrial hygiene, occupational medicine, and occupational health nursing) as well as three other disciplines likely to play a substantial role in the workplace of the future: employee assistance professionals, ergonomists, and occupational health psychologists.
Although each of the four traditional OSH professions emphasizes different aspects of OSH, members of all four professions share the common goal of identifying hazardous conditions, materials, and practices in the workplace and assisting employers and workers in eliminating or reducing the attendant risks. Occupational safety professionals, although concerned about all workplace hazards, have traditionally emphasized the prevention of traumatic injuries and workplace fatalities. Similarly, industrial hygienists, although they do not ignore injuries, have been a source of special expertise on the identification and control of hazards associated with acute or chronic exposure to chemical, biological, and physical agents. Occupational health nurses and occupational medicine physicians are distinguished by providing clinical care and programs aimed at health promotion and protection and disease prevention. These services include not only diagnosis and treatment of work related illness and injury, but also pre-placement, periodic, and return-to-work examinations, impairment evaluations, independent medical examinations, drug testing, disability and case management, counseling
In the late nineteenth century, Judith Sergeant Murray wrote about women’s intellect being equal- this helped narrow the gradations of freedom amongst white Americans.
Option: B
Explanation:
In the late nineteenth century there was a conflict in between white Americans about the freedom. Their fight against each other graded by the help of writer and other professionals who wrote about their strong points. Judith Sergeant Murray who was an American writer and advocate wrote about women's right.
Gender discrimination, women's right, feminism was the core area of writing in Judith Sergeant Murray's work. He compared women's ability with man's, their imagination, decision making capacity, judgemental motives etc.
