14. the length of the arc is found by using the formula 2*PI*r*angle/360
  the circle has a radius of 2 and the known angle is 90 degrees
 so you now have: 2 * pi * 2 * 90/360, since the answer needs to be in terms of PI, remove pi from the equation for now:
2*2 *90/*360 = 1
 the arc length = 1PI, or just PI

16. the area of the parallelogram is L x W :  9 *6 = 54
     the area of the circle is: PI *r^2 = pi * 3^2 = 28.26
 area of shaded region is subtracting the area of the circle from the parallelogram: 54 - 28.26 = 25.74 square inches

Answer:

38.5

Step-by-step explanation:

The formula for the area of the circle is \pi rx^{2} \\.

Since you have the diameter and you're told to use 3.14 as pi, all you need to do is to substitute.

The diameter is also 2 times the size of the radius so you divide 7 by 2.

So (3.14)(3.5)^{2} = 38.5
