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.

The white house is in the middle. Good riddle!
Answer:
The cost of living refers to the prices of goods and services needed to sustain an average level standard of living in an area
Explanation:
The cost of living refers to the cost of keeping up with a given standard of living. It is the amount Jamie would need to keep up with basic expenses such as food, housing, clothing and medical care. Cost of living compares the expense between living in two different areas. Jamie's cost of living is tied to his wages and it can be measured using what is called purchasing power parity.
Answer:
A) Design competition
Explanation:
Digital watch manufacturers and manufacturers of analog watches compete against each other because their products basically satisfy the same needs. Each one offers a very different product with its pros and cons, but even though their products are so different, they can be considered substitutes.
In the concept of innovation streams, Curtab is the innovator that is trying to create a sustainable competitive advantage because it works by designing an innovative product while its competitors rely on updating old designs.
Answer: 15.1875
Explanation: k = 81 units L = 16 units
(81 × 3/4) × (16÷4) = 243
Q =243
APL = Q / L
243 ÷ 16 = 15.1875 units of labour
