Find the surface area of the open circular cylinder shower=4 h= 7

Answers

Answer 1
Answer: Here we have a cylinder without a base on the top (though still one on the bottom)
Let's break down the surface area of this cylinder.
SA_(cyl)=LA_(cyl)+B
The surface area is equal to the lateral area plus the area of that one base.

The lateral area of any prism is equal to the perimeter of the base times the height.
LA=Ph
In this case, since the base is a circle, the perimeter is the circumfrence, which can be found using C = 2πr...r = 4, so C = 8π. h = 7, so LA = 56π.

The base is just the area of a circle, which can be found with this formula.
A_\odot=\pi r^2
r =4, so r² = 4×4 = 16, and the area of the base is = 16π.

SA = LA + B
SA = 56π + 16π
SA = 72π

In "I, Too," why does the speaker say "they" will be ashamed?

Answers

The speaker says they will be ashamed because they will see how beautiful he is.


This poem is in response to Whitman's "I Hear America Singing". In the poem Hughes, contrasts Whitman's idea that America is a place where everyone has value. However, Hughes does not see the same America as Whitman. People of his race are constantly tossed aside and banished to back rooms. They are not valued or respected. He tells the audience that "they" meaning the white people will be ashamed when they learn all that the African Americans have to offer the world.

Final answer:

In 'I, Too,' the speaker foresees that 'they' will feel shame for excluding and discriminating against him as his intrinsic value to the nation is eventually recognized.

Explanation:

  • In the poem I, Too, by Langston Hughes, the speaker predicts that 'they' will be ashamed because his presence and contributions as an African American will eventually be acknowledged as an integral part of America.
  • He implies that the exclusion and discrimination that he currently faces will be a source of shame for those who perpetrate it once they realize the beauty and value he adds to the country.
  • The use of 'I, too, am America' is a powerful assertion of the speaker's rightful place in the nation, despite being told to eat in the kitchen, which symbolizes segregation and marginalization.

Answers

Answer: The sentence that demonstrates the correct use of elongated hyphens is "Gideon and Francis took a difficult - but not interesting - science course".

Explanation: Elongated hyphens are added in a sentence to emphasize a particular idea. Therefore, they have the opposite effect of parenthesis, which minimize the information provided. Moreover, elongated hyphens give place to abrupt interruptions. The sentence "Gideon and Francis took a difficult - but not interesting - science course" is the one that uses the elongated hyphens in a correct way because what the writer wants to emphasize is the fact that the science course was not interesting.

The sentence that demonstrates the correct use of elongated hyphens is:

"Gideon and Francis took a difficult but not - interesting science - course." (option B)

What is a Hyphen?

A hyphen is a sign that is used to join words together. When they are used in an elongated format, it is because they are used to join two or more words that together help to qualify a noun.

Hence the sentence that demonstrates the correct use of elongated hyphens is: "Gideon and Francis took a difficult but not - interesting science - course."
