Answer:
There are total 5 layers.
Step-by-step explanation:
A multi-layer cake is in the shape of a right cylinder.
Height of the cake is = 20 cm
Radius is = 10 cm
Each of the cake layers has a volume of approximately 1,250 cm³.
Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.
Volume of the cylinder is given as:
![V=\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20h)
![1250=3.14\times(10)^{2}\times h](https://tex.z-dn.net/?f=1250%3D3.14%5Ctimes%2810%29%5E%7B2%7D%5Ctimes%20h)
![1250=314 h](https://tex.z-dn.net/?f=1250%3D314%20h)
![h=\frac{1250}{314}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B1250%7D%7B314%7D)
h = 3.98 or approximately height of 1 layer is 4 cm.
As the cake's height is 20 cm so, there are
layers in the cake.
Answer: There are 5 layers in the cake.
Same-side interior angles are supplementary, so add to 180°.
Opposite side exterior angles are equal.
Solve these by using the appropriate relation with the given expressions.
9) (x +134) +(x +64) = 180
.. 2x +198 = 180
.. x = (180 -198)/2 = -9
The angles are 125° (top) and 55° (bottom).
4+(-4)=4-4=0
4*|-2|=4*2=8
-4*|2|=-4*2=-8
|-4|*(-2)=4*(-2)=-8
4+2=6
the highest is 8 or 4*|-2|
