Find the area of the total circle and when you find that area, multiply it by 145/360 for that is how much of the circle that area is.
Area of circle, 
r^2 and 13.69 times 3.14 is 42.9866. Then multiply by 145/360 to get about 17.3 inches squared.
Is it supposed to be a attached picture to the question?
The hypotenuse can be solved by this formula. X^2 = 6^2 +6^2
X^2=64
Usually you cut it down to 8 but it wants the squared form so 64.
For A put 160 (division sign} 4.
For B put -40
Just multiply !!
so 1 inch = 5 miles
3.5 inch must be 3.5×5 = 17.5 miles
so the answer is 17.5 miles !!
