Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
Part 1) Find the area
we know that
The area of the shape is equal to the area of a quarter of circle minus the area of an isosceles right triangle
so

we have that the base and the height of triangle is equal to the radius of the circle

substitute

simplify
Factor 36

Part 2) Find the perimeter
The perimeter of the figure is equal to the circumference of a quarter of circle plus the hypotenuse of the right triangle
The circumference of a quarter of circle is equal to

substitute the given values

Applying the Pythagorean Theorem
The hypotenuse of right triangle is equal to

simplify

Find the perimeter

simplify
Factor 6

4 miles because there are 5280 ft in one mile so if you were to multiply that by 4 you would get 21120 ft
5% fail
so 100-5=95% are left
percent means parts out of 100
95% of 100 is

times 100=95
95 students are left assuming that the 5% that fail fail within 12 months
I agree with you you both of those are prime numbers so it cant be simplified
