**Riemann Sum and Definite Integral Evaluation**

The following sum:

\[
\sqrt{25 - \left(\frac{5}{n}\right)^2} \cdot \frac{5}{n} + \sqrt{25 - \left(\frac{10}{n}\right)^2} \cdot \frac{5}{n} + \cdots + \sqrt{25 - \left(\frac{5n}{n}\right)^2} \cdot \frac{5}{n}
\]

is a right Riemann sum for the definite integral

\[
\int_{0}^{b} f(x) \, dx
\]

where \( b = \) [ ],  
and \( f(x) = \) [ ].

**The limit of these Riemann sums as \( n \to \infty \) is**  

[ ].

This material is important for understanding how to approximate the area under a curve using Riemann sums, which in calculus forms the foundational concept of integration.
