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: (C) Transformational leadership style
Explanation:
The transformational leadership style is one of the most important leadership element as it inspire and also encourage the various types of innovate ideas.

Answer:
The correct answer is D. Real income effect.
Explanation:
Real income is defined as the monetary income of an individual, taking into account the effect of inflation. For example, if a person's nominal salary increases by 10% in one year, and inflation is 6% in that year, the actual income will have increased 4% in that year.
Answer: 180%
Explanation:
Return on investment = (operating income/sales) x (sales/total assets)
=> operating income / total assets
given Operating income=1,800,000
Total assets.1,000,000
Current liabilities.=810,000
Return on investment=1,800,000/1,000,00=1.8 X 100= 180%
