Find the area of the smaller part of the circle `x^2+y^2=a^2` cut off by the line `x=a/(sqrt(2))`

Explanation

To find the area of the smaller part of the circle \(x^2 + y^2 = a^2\) cut off by the line \(x = \frac{a}{\sqrt{2}}\), we can follow these steps:

### Step 1: Understand the Circle and Line
The equation of the circle is given by:
\[ x^2 + y^2 = a^2 \]
This represents a circle centered at the origin (0, 0) with a radius \(a\).
