I saw the image that should have been posted with this word problem.
The rolls of wrapping paper is cylindrical in shape.
Roll A : length = 30 inches ; diameter = 3 inches
Roll B : length = 24 inches ; diameter = unknown
Lateral surface area = 2 π r h
Lateral Surface area of Roll A = Lateral Surface area of Roll B
2 * 3.14 * 1.5in * 30in = 2 * 3.14 * r * 24 in
282.60 in² = 150.72 in * r
282.60 in² / 150.72 in = r
1.875 in = r
diameter is 2 times the radius = 1.875 in * 2 = 3.75 inches
The diameter of Roll B is 3.75 inches.
Total cats: 8
Total expense: y
Expense per lion: $8,000
Total lions: z
Expense per leopard: $6,000
Total leopards: 8 - z
Therefore, the equation becomes:
total expense = number of lions × expense per lion + number of leopards ×expense per leopard
y = 8000z + 6000(8 - z)
y = 2000z + 48000

Answer:
32 inches cubed
Step-by-step explanation:
Multiply the length by the width: 4*4=16
Multiply by 12: 16*1/2=8
Multiply by height: 4*8=32
Hope this helped!
