Answer:

Step-by-step explanation:
we know that
The measure of central angle ABC is
radians
so

subtends the complete circle
The area of the shaded sector is the area of a quarter circle
so
The area of a quarter circle is equal to

we have

substitute

You can apply the distance between points formula.
D =√[(diff. of x-coord.)² +(diff. of y-coord.)²]
D = √(2.5 -1.5)² +(3.5-4.5)²
D = √[1² +(-1)²] = √2
D ≈ 1.14142 units
Multiply by 0.1 mile
D = 1.14142 * 0.1 = 0.14142
D≈0.141 miles
1.2 is it as a decimal or 0.5
