Answer:
37.68 inches
Step-by-step explanation:
The equation for the circumference of the circle is:
We can substitute 6 in for "r" and 3.14 for "π":
20x + 4y
i’m not sure if this is 100 percent but i combined 8 + 12 since they were both x and then combined 5 + (-1) since they were both y then put in simplest form
3y+13=2y+2
y+13=2 (subtracting 2y from both sides)
y=-11 (subtracting 13 from both sides)

Answer:
Choice C (6)
Discussion:
Since it is an isosceles trapezoid the length of the two legs (i.e. AB = 5y-10 and CD = 2y+8) are equal. In other words,
5y - 10 = 2 y + 8
Subtract 2y from each side:
5y - 2y - 10 = 8
Now add 10 to each side
5y - 2y - 10 + 10 = 8 + 10 =>
3y + 0 = 18 =>
3y = 18 =>
y = 6
