Answer:
Diameter of circle while measuring vertically=3.5 cm
Diameter of circle while measuring Horizontally=3.6 cm
As you have not written by which instrument from geometry box you have measured the length of diameter.
1. By Scale i.e ruler 2. By Divider Or 3. By mere Observation i.e by comparing length
1.If you have done measurement by simply observation there are maximum possibility of having error.
2. Then if you have measured these lengths by scale or ruler there is very less chances of getting error in measurement of length because sometimes divison in scale varies i.e if a point lies between 4.5 to 4.6 we can't say exactly whether it is 4.5 or 4.6.
3. So it is better to compare line segments by Divider.There is no chances of getting error.
Most probably you have measured Diameter by ruler, Due to that you have faced the problem.

Why?</h2>
It's common to find more than just one equivalent expression to other expression since a number can be written in several ways and it will be the same.
The given expression is:
![10q+5](https://tex.z-dn.net/?f=10q%2B5)
The given expression can be written like:
![10q+5=5q+5q+5](https://tex.z-dn.net/?f=10q%2B5%3D5q%2B5q%2B5)
or
![10q+5=5(2q+1)](https://tex.z-dn.net/?f=10q%2B5%3D5%282q%2B1%29)
We can also write the expression using fractions!
![10q+5=10(q+\frac{1}{2})](https://tex.z-dn.net/?f=10q%2B5%3D10%28q%2B%5Cfrac%7B1%7D%7B2%7D%29)
Have a nice day!
