$\frac{\pi }{2}$

Step-by-step explanation:

One way to do this would be to find the circumference of the entire circle and divide it by 4, considering that the arc measure is 90 degrees

The radius is 1, and the circumference can be found by taking $2\pi r$

So, the circumference of this circle is $2\pi$

Now, all we have to do is divide that by four to get our answer

$\frac{2\pi }{4} = \frac{\pi }{2}$
