Very easy:
Since there is no involvement of y so simply draw a vertical line at x=1.And shade the part which is describing the x values.
Hence,
You will shade all the part which is on the left of the vertical line.As there is an equal sign too,so the vertical line will be a solid line instead of dotted line.

A. 24 miles
Explanation:
the area inside a circle is given by:
where r is the radius of the circle.
In this problem, we know the circular area:
So we can re-arrange the equation above to find r, the radius:
so, the radius of the circular area is 24 miles.
