Find the surface area of the cylinder. Use the approximation 3.14 for pi.
Height = 8 yards
Width = 7 yards
A. 252.77 yards
B. 252.77 square yards
C. 329.7 square yards
D. 577.76 square yards
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πrh + 2πr^2
Given:
Height (h) = 8 yards
Radius (r) = Width/2 = 7/2 = 3.5 yards
Substituting the given values into the formula:
Surface Area = 2 * 3.14 * 3.5 * 8 + 2 * 3.14 * 3.5^2
Surface Area = 175.84 + 153.86
Surface Area = 329.7 square yards
Therefore, the surface area of the cylinder is approximately 329.7 square yards.
The correct answer is option C. 329.7 square yards.
Find the surface area of the cylinder. Use the approximation of 3.14 for pi.
Height = 3 yards
Width = 2 yards
A. 62.8
B. 75.36
C. 32.97
D. 25.12
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πrh + 2πr^2
Given:
Height (h) = 3 yards
Radius (r) = Width/2 = 2/2 = 1 yard
Substituting the given values into the formula:
Surface Area = 2 * 3.14 * 1 * 3 + 2 * 3.14 * 1^2
Surface Area = 18.84 + 6.28
Surface Area = 25.12
Therefore, the surface area of the cylinder is approximately 25.12 square yards.
The correct answer is option D. 25.12 square yards.
A can of olives has 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.
A. 75.36
B. 150.72
C. 376.8
D. 131.88
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πrh + 2πr^2
Given:
Diameter = 6 inches
Radius (r) = Diameter/2 = 6/2 = 3 inches
Height (h) = 4 inches
Substituting the given values into the formula:
Surface Area = 2 * 3.14 * 3 * 4 + 2 * 3.14 * 3^2
Surface Area = 75.36 + 56.52
Surface Area = 131.88
Therefore, the label on the outside of the can will require approximately 131.88 square inches of paper.
The correct answer is option D. 131.88 square inches.
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.
A. 62.8 square inches
B. 94.2 square inches
C. 37.68 square inches
D. 301.44 inches
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πrh + 2πr^2
Given:
Diameter = 6 inches
Radius (r) = Diameter/2 = 6/2 = 3 inches
Height (h) = 2 inches
Substituting the given values into the formula:
Surface Area = 2 * 3.14 * 3 * 2 + 2 * 3.14 * 3^2
Surface Area = 37.68 + 56.52
Surface Area = 94.2
Therefore, the surface area of the cheese wheel is 94.2 square inches.
The correct answer is option B. 94.2 square inches.
