Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: 
The radius is 3 inches.

The height is three times the radius.
Multiply the radius by three to get the height.

The height is 9 inches.
Use the formula to find the volume.

The exact volume is 81
inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
Hope this helps! Don’t mind the part I crossed off.
I think it'd be 10in. If you cut it into three parts, where the bottom is sectioned off from the other two rectangles, the two rectangles on the side both have an area of 3in, so together they'd be 6in. The rectangle on the bottom has a length of 4 and a width of 1, so it'd be 4in... add those together and get 10in. Hope this helps
