Can you make the question more clear i would love to help?
Given:
The equation is
![\dfrac{a}{b}=\dfrac{b}{c}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%7D%7Bb%7D%3D%5Cdfrac%7Bb%7D%7Bc%7D)
To find:
The value of
.
Solution:
We have,
![\dfrac{a}{b}=\dfrac{b}{c}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%7D%7Bb%7D%3D%5Cdfrac%7Bb%7D%7Bc%7D)
On cross multiplication, we get
![a\times c=b\times b](https://tex.z-dn.net/?f=a%5Ctimes%20c%3Db%5Ctimes%20b)
![ac=b^2](https://tex.z-dn.net/?f=ac%3Db%5E2)
![b^2=ac](https://tex.z-dn.net/?f=b%5E2%3Dac)
Therefore, the value of
is
.
To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.
120 because when you round 119.63, the .6 rounds to a whole number, making it 120
