Area of circle is 76.44 square units.

We are given that

Base of one sector = b = 1.95 units

Height of sector = h = 4.9 units

Total number of sectors = 16

Area of one sector is equal to area of triangle (approximately)

Area of sector = \frac{1}{2} \times b \times h

Using the formula

Area of one sector= \frac{1}{2} \times (1.95) \times (4.9)

= 4.7775 square units

Area of circle A = 16 × Area of sector

Area of circle A = 16 × 4.7775

= 76.44 square units

Hence, Area of circle is 76.44 square units.

Option D is true.

Analyze this document by providing its hipp: historical context, intended audience, author’s purpose, and author’s point of view
BartSMP [9]

To establish a conclusion about a document, the following aspects must be taken into account:

  • Historical context.
  • Target audiences.
  • Author's goal.
  • Author's point of view.

These points will allow us to establish our point of view regarding that text.

<h3>What is the historical context of a text? </h3>

The historical context of a text refers to the moment in history in which the event that is being reported in the document occurred. For example, there are many documents whose historical context are world wars.

The historical context has a great influence on the events that occur in a text because the lives of its characters can be affected by what happens. For example, in the Diary of Anne Frank, her life underwent several changes due to the historical context of the Second World War.

<h3>What is the target audience? </h3>

The target audience of a text is a term that refers to the audience that the text is addressed to. The texts can be classified in this way because this category determines different characteristics of the texts such as:

  • Language type.
  • Topics
  • Interests
  • Culture origin.

<h3>How does the author's point of view and his goal affect a text? </h3>

The texts are what his/her author wants, therefore, when a writer has an idea for a text, he presents his point of view without modifications to establish his position regarding a topic. For example, in scientific investigations the authors defend a hypothesis by means of arguments and establish their purpose of arguing the idea.

The aspects mentioned above influence the way we read and interpret a document because we are learning about a topic from the author's point of view. However, this does not mean that our position on this issue is the same as the author's. On the contrary, this allows us to discern his approach.

Note: This question is incomplete because the document is missing. However I can answer it based on my prior knowldge.
