15.5 I believe but don’t hold me to it!
Answer:c
Step-by-step explanation:
The Answer is C.
Your answer is: 3. 3 hours, 18 minutes
Lets get started :)
The First question:
Diameter = 20 ft
Radius =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
of 20 (diameter) = 20 ft
Area formula of a circle is
A =
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r²
=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(10)²
=100
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
ft²
≈ 314 ft²The answer will be the second optionThe Second question:
radius of circle = 12mm divided into 20 sectors area
A =
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r²
=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(12)²
= 144
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
ft²
Divide into 20 equal sector areas =
≈ 22.6 mm²Your answer will be the third optionThe Third Question:
90°, sector area = 36
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
, Radius = ?
![\frac{angle}{360} = \frac{sector}{ \pi (r)^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bangle%7D%7B360%7D%20%3D%20%5Cfrac%7Bsector%7D%7B%20%5Cpi%20%28r%29%5E2%7D%20)
![\frac{90}{360} = \frac{36 \pi }{ \pi r^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B90%7D%7B360%7D%20%3D%20%5Cfrac%7B36%20%5Cpi%20%7D%7B%20%5Cpi%20r%5E2%7D%20)
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
and
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
cancels out
We can now cross multiply
360 × 36 = 90r²
12960 = 90r²
Divide by 90 on either side
![\frac{12960}{90} = \frac{90r^2}{90}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12960%7D%7B90%7D%20%3D%20%5Cfrac%7B90r%5E2%7D%7B90%7D%20)
144 = r²
Take squareroot
x = 12 inYour answer will be the third option
Answer:
there are 5 types of point of views
please brainliest me
Step-by-step explanation:
1rst person: Writing in first person means writing from the author's point of view or perspective. This point of view is used for autobiographical writing as well as narrative.
2 person: The second-person point of view belongs to the person (or people) being addressed. This is the “you” perspective. Once again, the biggest indicator of the second person is the use of second-person pronouns: you, your, yours, yourself, yourselves.
3 person: In the third-person point of view, a narrator tells the reader the story, referring to the characters by name or by the third-person pronouns he, she, or they.
4 person: The term fourth person is also sometimes used for the category of indefinite or generic referents, which work like one in English phrases such as "one should be prepared" or people in people say that..., when the grammar treats them differently from ordinary third-person forms."
5 person:From a fifth person perspective, one starts to “feel” the system in a different way, recognizing that one's own perspective on and in the Anthropocene is merely a perspective, which itself is a perspective, which in turn is a perspective.
