The length of a diameter of circle x² + y² = a² is?

4a
2a
3a
None of these

Explanation

Let's analyze the given circle equation:
$x^{2} + y^{2} = a^{2}$

This is the standard form of a circle with:

Center at the origin $(0, 0)$
Radius $r = a$ (since $r^{2} = a^{2}$ )

The diameter of a circle is twice the radius:

$Diameter = 2 \times radius = 2 \times a = 2 a$
