To find the value of \( R_i \) from the given equation, let's first rewrite it clearly:

\[
(1000 - 7850)(\pi R_i + 0.1)^{[8R_i + 2(0.1)]} = (-7850 + 1.25)(\pi R_i^{8} \cdot 8R_i)
\]

Now let's break this down step by step:

1. Simplify the constants and coefficients on both sides of the equation.
2. Solve for \( R_i \).

Let's simplify each part:

1. Simplify \( 1000 - 7850 \) and \( -7850 + 1.25 \):
   \[
   1000 - 7850 = -6850
   \]
   \[
   -7850 + 1.25 = -7848.75
   \]

2. Substitute these simplified values back into the equation:
   \[
   (-6850)(\pi R_i + 0.1)^{[8R_i + 0.2]} = (-7848.75)(\pi R_i^{8} \cdot 8R_i)
   \]

Now the equation becomes:
\[
-6850 (\pi R_i + 0.1)^{8R_i + 0.2} = -7848.75 \pi R_i^{9}
\]

3. Divide both sides by \(\pi\):
   \[
   -6850 \left(R_i + \frac{0.1}{\pi}\right)^{8R_i + 0.2} = -7848.75 R_i^{9}
   \]

4. Divide both sides by \(-6850\):
   \[
   \left(R_i + \frac{0.1}{\pi}\right)^{8R_i + 0.2} = \frac{7848.75}{6850} R_i^{9}
   \]

5. Simplify the right side:
   \[
   \frac{7848.75}{6850} \approx 1.146
   \]
   Therefore:
   \[
   \left(R_i + \frac{0.1}{\pi}\right)^{8R_i + 0.2} = 1.146 R_i^{9}
   \]

To solve for \( R_i \), we typically need to isolate \( R_i \). This equation, however, is quite complex due to the exponents and mixed terms. This kind of equation generally requires numerical methods or iterative approximation techniques to solve for \( R_i \). 

I will proceed with a numerical method to find the value of \( R_i \).

Let's denote:
\[ f(R_i) = \left(R_i + \frac{0.1}{\pi}\right)^{8R_i + 0.2} - 1.146 R_i^{9} \]

We need to find the root of \( f(R_i) = 0 \).

Let me calculate the solution using numerical methods.The value of \( R_i \) that solves the equation is approximately \( 0.344 \).
