The answer is 16 inches, we can get the medians length of the trapezoid by using the formula: EF = (BC + AD) / 2. Given: EF = the medians length; BC = top base
= 12 inches; and AD = bottom base = 16 inches.
Therefore:
EF = (12 + 16)/2
EF = 28 / 2
EF = 14 inches’ medians
length is the average of the two bases of trapezoid.

Answer:
True False True
Step-by-step explanation:
1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE
2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.
3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE
