Answer:
16 rolls of ribon
Step-by-step explanation:
C = Dπ
d = r x 2
d = 100 x 2
d = 200
C = 200 x 3.14
C = 628
628 / 40 = 15.7
she should buy 16 rolls
The circumstances of the circle is 62.83
Hope this helps. If you have any further question ask in comments.
Radius is the distance from the centre to any point in the circumference. i.e. radius =
![\sqrt{ (-7-8)^{2} + (-1-7)^{2} } = \sqrt{ (-15)^{2} + (-8)^{2} } \\ = \sqrt{225+64} = \sqrt{289} =17](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%28-7-8%29%5E%7B2%7D%20%2B%20%28-1-7%29%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B%20%28-15%29%5E%7B2%7D%20%2B%20%28-8%29%5E%7B2%7D%20%7D%20%5C%5C%20%3D%20%5Csqrt%7B225%2B64%7D%20%3D%20%5Csqrt%7B289%7D%20%3D17)
radius = 17 units
Answer:
4096 is the simplified form of ![\left(2^{3}\right)^{4}](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D)
Option: B
Step-by-step explanation:
Given that ![\left(2^{3}\right)^{4}](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D)
represents 2 to the power 3 that means the number appears three times in multiplying.
![2^{3}=(2 \times 2 \times 2)](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D%282%20%5Ctimes%202%20%5Ctimes%202%29)
![2^{3}=(2 \times 2 \times 2)](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D%282%20%5Ctimes%202%20%5Ctimes%202%29)
![2^{3}=(4 \times 2)](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D%284%20%5Ctimes%202%29)
![2^{3}=8](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D8)
represents 2³ to the power 4 means the number 4 appears four times in multiplying.
![\left(2^{3}\right)^{4}=8 \times 8 \times 8 \times 8](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D%3D8%20%5Ctimes%208%20%5Ctimes%208%20%5Ctimes%208)
![\left(2^{3}\right)^{4}=64 \times 8 \times 8](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D%3D64%20%5Ctimes%208%20%5Ctimes%208)
![\left(2^{3}\right)^{4}=512 \times 8](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D%3D512%20%5Ctimes%208)
![\left(2^{3}\right)^{4}=4096](https://tex.z-dn.net/?f=%5Cleft%282%5E%7B3%7D%5Cright%29%5E%7B4%7D%3D4096)
Hence the simplified form of
is 4096.
