Step 1:

The curve is $\"\"$ .

Observe the graph, the interval of $\"\"$ is $\"\"$ .

Definition of the arc length:

If the curve $\"\"$ , $\"\"$ , then the length of the curve is defined as,

$\"\"$ .

Here $\"\"$ and $\"\"$ .

Consider $\"\"$ .

Differentiate with respect to $\"\"$ on each side.

$\"\"$

Substitute $\"\"$ and limits of $\"\"$ in arc length formula.

$\"\"$

Solution:

The arc length of the curve $\"\"$ is $\"\"$ .
