Answer:
3619.11 or 3619.1
Step-by-step explanation:
i don't really know how to explain but that's what i got
We know that
<span>An<span> exterior angle</span></span><span> is one that has its vertex at an outer point of the circumference
</span><span>The measure of the external angle is the semidifference of the arcs that it covers
</span>
so
∠NOP=(70-30)/2-----> 20°
the answer is
<span>∠NOP=20</span>°
The area of flying disk is 452.16 square centimeters
Step-by-step explanation:
The disc is in circular shape so we will use the formulas for circle in this question.
Given
Circumference = C = 75.36 centimeters
We have to find the area of the disc for which we have to find the radius first.
Let r be the radius
Then
Circumference is given by:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
putting the values
![75.36 = 2*3.14*r\\75.36 = 6.28r](https://tex.z-dn.net/?f=75.36%20%3D%202%2A3.14%2Ar%5C%5C75.36%20%3D%206.28r)
Dividing both sides by 6.28
![\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm](https://tex.z-dn.net/?f=%5Cfrac%7B6.28r%7D%7B6.28%7D%20%3D%20%5Cfrac%7B75.36%7D%7B6.28%7D%5C%5Cr%20%3D%2012%5C%20cm)
The area of circle is given by:
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
Putting the values
![A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2](https://tex.z-dn.net/?f=A%20%3D%203.14%20%2A%20%2812%29%5E2%5C%5CA%20%3D%203.14%2A144%5C%5CA%20%3D452.16%5C%20cm%5E2)
Hence,
The area of flying disk is 452.16 square centimeters

Hello from MrBillDoesMath!
Answer:
1 cubic inch.
Discussion:
If each side of the sugar cube is 1, the volume, which is the product of the length, width, and height, equals
1 * 1 *1 =
1 cubic inch.
Thank you,
MrB
Answer= 1 million
For an approximation we don't use exact numbers. Seeing as Pennsylvania has a population of around 12.6 million and Ohio has a population near 11.5 million, there is about a difference of 1 million when comparing the populations.
