The formula for the surface area of a cylinder is given by:
Surface Area = 2πrh + 2πr^2
where r is the radius and h is the height.
Plugging in the values from the problem, we have:
Surface Area = 2(3.14)(5)(10) + 2(3.14)(5^2)
Surface Area = 314 + 157
Surface Area = 471 square inches
Therefore, the surface area of the cylinder is 471 square inches.

The formula for the surface area of a cylinder is given by:
Surface Area = 2πrh + 2πr^2
where r is the radius and h is the height.
Plugging in the values from the problem, we have:
Surface Area = 2(3.14)(7)(8) + 2(3.14)(7^2)
Surface Area = 351.36 + 307.44
Surface Area = 658.8 square yards
Therefore, the surface area of the cylinder is approximately 658.8 square yards.

Apologies for the mistake. Let's calculate the correct surface area of the cylinder.
The formula for the surface area of a cylinder is:
Surface Area = 2πrh + 2πr^2
Given that the height (h) is 8 yards and the radius (r) is 7 yards, we can substitute these values into the formula:
Surface Area = 2(3.14)(7)(8) + 2(3.14)(7^2)
Surface Area = 351.36 + 307.44
Surface Area = 658.8 square yards
Therefore, the surface area of the cylinder is approximately 658.8 square yards.

The formula for the surface area of a cylinder is given by:
Surface Area = 2πrh + 2πr^2
where r is the radius and h is the height.
Plugging in the values from the problem, we have:
Surface Area = 2(3.14)(2)(3) + 2(3.14)(2^2)
Surface Area = 37.68 + 25.12
Surface Area = 62.8
Therefore, the surface area of the cylinder is 62.8 square yards.

The surface area of the can, excluding the top and bottom, can be calculated using the formula for the lateral surface area of a cylinder:
Lateral Surface Area = 2πrh
where r is the radius (half of the diameter) and h is the height.
Given that the diameter is 6 inches, the radius (r) is 3 inches, and the height (h) is 4 inches, we can substitute these values into the formula:
Lateral Surface Area = 2(3.14)(3)(4)
Lateral Surface Area = 75.36 square inches
Therefore, approximately 75.36 square inches of paper will be needed for the label on the outside of the can.
A wheel of cheese has a diameter of 6 inches and a height of 2 inch. A chef is making an appetizer where the cheese will be covered with pastry. To know how much pastry is needed, the chef wants to know the surface area of the cheese wheel. What is the total surface area of the cheese wheel in square inches?

The formula for the surface area of a cylinder can be used to find the total surface area of the cheese wheel.
Total Surface Area = 2πrh + 2πr^2
Given that the diameter is 6 inches, the radius (r) is 3 inches, and the height (h) is 2 inches, we can substitute these values into the formula:
Total Surface Area = 2(3.14)(3)(2) + 2(3.14)(3^2)
Total Surface Area = 37.68 + 56.52
Total Surface Area = 94.2 square inches
Therefore, the total surface area of the cheese wheel is approximately 94.2 square inches.
