Question

Calculate the area of the label on the can of salmon, to the nearest square inch.

Answer 1

16 square inches

Explanation:

Remember :

Area of label = Lateral Surface Area of a Cylinder

Solving :

⇒ LSA = 2πrh

⇒ LSA = 2 × π × 3 1/2 × 1/2 × 1 1/2

⇒ LSA = π × 7/2 × 3/2

⇒ LSA = 21π/4

⇒ LSA ≈ 16 square inches

Answer 2

Can is cylinder

Label is lateral surface area

• Radius=3-1/2÷2=7/2÷2=7/4in
• Height=1-1/2=3/2in

LSA

• 2πrh
• 2π(7/4)(3/2)
• 42π/8
• 16.5in²
