Please help the problem is below.
Anna007 [38]

Answer:

1. $1,122
2. $485.25

3. $440

4. $2,047.25

Step-by-step explanation:

1. 22 feet * 17 feet = 374 square feet * $3 per square foot = $1,122
2. 17 feet * 10 feet * 4 walls = 680 square feet. 680 feet - (7ft*3ft for the door) - (2*2ft*3ft for the windows) = 647 square feet * $0.75 per square foot = $485.25
3. 374 square feet/ $88 per gallon = 4.25 gallons which rounds up to 5 gallons, and 5 gallons at a cost of $88 per gallon = $440
4. $1,122 + $485.25 + $440 = $2,047.25

cylinder A has a volume of 360 cm3. Cylinder B has a base and height identical to that of cylinder B, but leans to the right in
irina1246 [14]
If the height is measured between the parallel ends of the cylinder, the volume is identical:
  360 cm³.

_____
If the "height" is measured along the central axis of the cylinder, there is insufficient information to determine the volume.

The slant length of a prism (even a cylindrical one) is immaterial. What matters to the volume is the area of the base and the distance between the planes of the bases (height).
