The expression that represents the shaded region is 1/4
<h3>How to determine the expression?</h3>
The figure represents the given parameter
From the figure, we can see that:
- The complete figure is a circle
- Part of it is shaded
- The remaining part is unshaded
From the figure, we can also see that:
Shaded region = 1/4 of the whole circle
In this case, we set the whole circle to 1
So, we have
Shaded region = 1/4 of 1
Rewrite as
Shaded region = 1/4 x 1
Evaluate
Shaded region = 1/4
Hence, the expression of the shaded region is 1/4
