Answer:
The correct answer is 63 cubic inches.
Step-by-step explanation:
Dali rolled up his painting and placed it in a cylinder 2 inches diameter.
Diameter of the painting is 2 inches. This also implies diameter of the cylinder is 2 inches.
Radius of the cylinder is 1 inch.
Length of the cylinder is 20 inches.
Volume of the cylinder is given by π × 
× h = π × 
× 20 = 20π = 62.85 cubic inches ≈ 63 cubic inches.
Therefore the volume of the cylinder in which Dali placed his painting is given by 63 cubic inches.
A parallelogram is a four-sided figure with opposite sides parallel.

You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.
8 x 2 = 16
The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that.
3 x 1 = 3
16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)
