To find the surface area of a cylinder, you need to calculate the area of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = (2 * π * r^2) + (2 * π * r * h)
Given that the approximation for π is 3.14, you need to plug in these values into the formula to find the surface area of the cylinder.
However, since you haven't provided the values for the radius (r) and height (h) of the cylinder, I'm unable to calculate the exact surface area.

Now that I have the values for the radius and height of the cylinder, I can calculate the surface area.
Using the formula:
Surface Area = (2 * π * r^2) + (2 * π * r * h)
Plugging in the values:
Surface Area = (2 * 3.14 * 7^2) + (2 * 3.14 * 7 * 8)
Surface Area = (2 * 3.14 * 49) + (2 * 3.14 * 7 * 8)
Surface Area = (6.28 * 49) + (6.28 * 56)
Surface Area = 307.72 + 351.52
Surface Area = 659.24 square units
Therefore, the surface area of the cylinder is approximately 659.24 square units.
the length of the cylinder from left to right is 7 and the height is 8
now another one is 2,3
Using the same formula for the surface area of a cylinder:
Surface Area = (2 * π * r^2) + (2 * π * r * h)
Given that the length from left to right is 2 (which we assume to be the diameter) and the height is 3, we can find the radius (r) by dividing the diameter by 2:
r = 2/2 = 1
Now, we can plug in the values into the formula:
Surface Area = (2 * 3.14 * 1^2) + (2 * 3.14 * 1 * 3)
Surface Area = (2 * 3.14 * 1) + (2 * 3.14 * 1 * 3)
Surface Area = (6.28 * 1) + (6.28 * 3)
Surface Area = 6.28 + 18.84
Surface Area ≈ 25.12 square units
Therefore, the surface area of the cylinder is approximately 25.12 square units.
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.(1 point) Responses 376.8 376.8 131.88 131.88 75.36 75.36 150.72
To find the surface area of the can and therefore determine the amount of paper needed for the label, we need to calculate the lateral surface area.
The lateral surface area of a cylinder is given by the formula:
Lateral Surface Area = 2 * π * r * h
Given that the diameter of the can is 6 inches, we can find the radius (r) by dividing the diameter by 2:
r = 6/2 = 3 inches
Now, we can plug in the values into the formula:
Lateral Surface Area = 2 * 3.14 * 3 * 4
Lateral Surface Area = 2 * 3.14 * 3 * 4
Lateral Surface Area = 6.28 * 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? Use 3.14 for pi.(1 point) Responses 94.2 square inches 94.2 square inches 62.8 square inches 62.8 square inches 301.44 square inches 301.44 square inches 37.68 square inches
To find the surface area of the cheese wheel, we need to calculate the area of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = (2 * π * r^2) + (2 * π * r * h)
Given that the diameter of the cheese wheel is 6 inches, we can find the radius (r) by dividing the diameter by 2:
r = 6/2 = 3 inches
Now, we can plug in the values into the formula:
Surface Area = (2 * 3.14 * 3^2) + (2 * 3.14 * 3 * 2)
Surface Area = (2 * 3.14 * 9) + (2 * 3.14 * 3 * 2)
Surface Area = (6.28 * 9) + (6.28 * 6)
Surface Area = 56.52 + 37.68
Surface Area = 94.2 square inches
Therefore, the total surface area of the cheese wheel is approximately 94.2 square inches.
