So, the answer is 2 x 2 x 2 x 7 or 2^3 x 7
        
             
        
        
        
Difference between 25 and 35 = 35 -25 
                                                 = 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
                                                                 = (2/7) * 100
                                                                 = 200/7
                                                                 = 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you
have understood the method used to solve this problem. Hopefully you
can do such type of problems without needing any help.

Answer:
The integral for the arc of length is:
 
By using Simpon’s rule we get: 1.5355453
And using technology we get:  2.3020
The approximation is about 33% smaller than the exact result.
Explanation:
The formula for the length of arc of the function f(x) in the interval [a,b] is:
![\displaystyle\int_a^b \sqrt{1+[f'(x)]^2}dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint_a%5Eb%20%5Csqrt%7B1%2B%5Bf%27%28x%29%5D%5E2%7Ddx) 
We need the derivative of the function:
 
And we need it squared:
![[f'(x)]^2=\frac{1}{x^2}](https://tex.z-dn.net/?f=%5Bf%27%28x%29%5D%5E2%3D%5Cfrac%7B1%7D%7Bx%5E2%7D) 
Then the integral is:
 
Now, the Simposn’s rule with n=4 is:
 
In this problem:
 
So, the Simposn’s rule formula becomes:
 
Then simplifying a bit:
 
Then we just do those computations and we finally get the approximation via Simposn's rule:
 
While when we do the integral by using technology we get: 2.3020.
The approximation with Simpon’s rule is close but about 33% smaller:
