cylindrical container is to be constructed to be open at the top with a volume of 27π cubic meters using the least amount of mat
Llana [10]

Answer:

radius comes out to be 3 m

height of the cylinder comes out to be 3m

Explanation:

given

volume of cylinder = 27π m³

π r² h = 27π

   r² h = 27.............(1)

surface area of cylinder open at the top

S = 2πrh + π r²

S = 2\pi \dfrac{27}{r} + \pi r^2

\frac{\mathrm{d} s}{\mathrm{d} r}=\frac{\mathrm{d}}{\mathrm{d} r} (2\pi \dfrac{27}{r} + \pi r^2)

\frac{\mathrm{d} s}{\mathrm{d} r}=54\pi \dfrac{-1}{r^2}+2\pi r

\frac{\mathrm{d} s}{\mathrm{d} r}=0

for least amount of material requirement.

\dfrac{54\pi }{r^2} = 2\pi r\\r=3m

hence radius comes out to be 3 m

for height put the value in the equation 1

so, height of the cylinder comes out to be 3m

gogolik [260]

Answer:

C. dismiss them.

Explanation:

The American Psychological Association is a scientific organization and it serves as an umbrella body for the professional psychologists practicing in the United States of America. This professional organization was founded by Granville Stanley Hall in July, 1892 and it has become the largest professional body with over 120,000 members such as scientists, consultants, clinicians, educators etc.

Basically, the American Psychological Association is saddled with the responsibility of providing professional certifications to psychologists and assisting in the advancement of human well-being.

If a psychologist violates his or her ethical obligations but breaks no laws, the American Psychological Association could take action and dismiss or censure them. This is done so as to serve as deterrent to other psychologists and to help maintain the core values, objectives and mission of the professional organization.
