The formula for the surface area of a cylinder is given by:

Surface Area = 2πr^2 + 2πrh

Plug in the given values:

Surface Area = 2 * 3.14 * 5^2 + 2 * 3.14 * 5 * 10
Surface Area = 2 * 3.14 * 25 + 2 * 3.14 * 5 * 10
Surface Area = 157 + 314
Surface Area = 471 square inches

Therefore, the surface area of the cylinder is 471 square inches. Answer: 471 square inches

The formula for the surface area of a cylinder is given by:

Surface Area = 2πr^2 + 2πrh

We can rearrange the formula to solve for the radius:

r = √((Surface Area - 2πrh) / (2π))

Plug in the given values:

Surface Area = 7 square yards
Height = 8 yards
pi (π) ≈ 3.14

r = √((7 - 2 * 3.14 * r * 8) / (2 * 3.14))

Using trial and error, we can calculate that the radius is approximately 2.5 yards.

Now, we can calculate the area of the cylinder:

Area = πr^2 * height

Area = 3.14 * (2.5^2) * 8
Area = 3.14 * 6.25 * 8
Area = 157 * 8
Area = 1256 square yards

Therefore, the area of the cylinder is 1256 square yards. Answer: 1256 square yards

Apologies for the confusion. Let's calculate the surface area using the given options.

Given options:
1) 329.7 square yards
2) 577.76 square yards
3) 252.77 yards
4) 252.77 square yards

Using the formula for the surface area of a cylinder:

Surface Area = 2πr^2 + 2πrh

Let's plug in the given values:

Surface Area = 2 * 3.14 * r^2 + 2 * 3.14 * r * 8

We need the value of r to proceed. Unfortunately, the surface area alone is not sufficient to determine the value of r or the exact surface area.

Thus, none of the given options exactly matches the surface area.

Answer 9

[AI-generated answer — Bot GPT 3.5]

The formula for the surface area of a cylinder is given by:

Surface Area = 2πr^2 + 2πrh

Plugging in the given values:

Surface Area = 2 * 3.14 * (2^2) + 2 * 3.14 * 2 * 3
Surface Area = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3
Surface Area = 25.12 + 37.68
Surface Area = 62.8

Therefore, the surface area of the given cylinder is 62.8 square yards. Answer: 62.8

Answer 10

A can of olives has a diameter of 6 inches and a height of 4 inches. How many square inches of paper will be needed for the label on the outside of the can? Use 3.14 for pi

To find the surface area of the label needed for the outside of the can, we need to calculate the lateral surface area of the cylinder, which is the curved surface area without the top and bottom areas.

The lateral surface area of a cylinder is given by:

Lateral Surface Area = 2πrh

Given:
Diameter = 6 inches, which means radius = 6/2 = 3 inches
Height = 4 inches

Lateral Surface Area = 2 * 3.14 * 3 * 4
Lateral Surface Area = 75.36 square inches

Therefore, 75.36 square inches of paper will be needed for the label on the outside of the can. Answer: 75.36
