Lateral area of a cylinder A is :
A = 2 π r h
We use this formula to find area of one label
π = 3.14, r = 1.5 inches and h = 3 inches.
A = 3.14 ×1.5×3
A= 14.13 inch²
1 inch² = 0.01 $
Therefore 14.13 inch² = 14.13 × 0.01 = 0.14 $
Each label will cost 0.14 $
400,000 labels will cost:
400, 000 × 0.14 = 56,000
Therefore it would cost 56,000 $ to produce 400,000 labels
