The longest piece is 25 inches and the shortest piece is 11 inches.
(36/2) - (14/2) = shortest piece
18 - 7 = 11 (shortest piece)
36 - 11 = 25 (longest piece)
25 - 11 = 14 inches difference between the pieces
Answer:
.
Step-by-step explanation:

Answer: y=x-4
Step-by-step explanation: The y value is exactly x minus four.
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.
Then, using the circle area formula, the area of the 1/9 circle would be:
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57
