Answer:

276 square cm

Step-by-step explanation:

We are solving for the lateral area of the cylinder soup can. This is the area of its side (NOT its bases).

The side of a can is a rectangle, so its area is:

[tex]A=l\cdot w[/tex]

where [tex]l[/tex] = length, [tex]w[/tex] = width.

We are given that:   [tex]l = 11\text{ cm}[/tex].

We need to solve for the rectangle's width, which is the same as the circumference of the circle base:

[tex]C = \pi d =w[/tex]

↓ plugging in the given [tex]d=8\text{ cm}[/tex]

[tex]w = 8\pi[/tex]

Plugging these dimensions in the above area formula:

[tex]A=11 \cdot 8\pi[/tex]

[tex]\boxed{A\approx276\text{ cm}^2}[/tex]

So, the label that covers the lateral area of the soup can has an area of approximately 276 square centimeters.

Answer:

276 square cm

Step-by-step explanation:

Understanding the question

We are given the dimensions of a can of soup (in the shape of a cylinder) and we are given that a paper label is large enough to cover the lateral surface area.

Given this we are asked to find the area of the label.

The lateral surface area is the area of an object excluding the areas of the base (top and bottom)

To find the lateral surface area of a cylinder we use the following formula

[tex]LSA=2\pi rh[/tex]

Where

  • r = radius
  • h = height

Finding the lateral surface area

If you look at the image of the can of soup we are given the following dimensions

  • Height = 11 cm
  • Diameter = 8 cm

We can convert diameter to radius by dividing by 2

Thus, radius = 8/2 = 4 cm

We now plug these values into the formula for lateral surface area

LSA = 2πrh

r = 4 , h = 11

LSA = 2π(4)(11)

LSA = 2π(44)

LSA = π88

LSA = 276 (rounded)

The area of the label is 276 square centimeters
