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 poi
To find the surface area of the can, we need to find the area of the curved surface, as well as the areas of the two circular bases.
The curved surface area of a cylinder can be found by multiplying the circumference of the base by the height. The circumference of the base is equal to the diameter times pi (π). So the curved surface area is 6 * 3.14 * 4 = 75.36 square inches.
The area of each circular base is equal to half the area of a circle with a diameter of 6 inches. The formula for the area of a circle is A = πr^2, where r is the radius. Since the diameter is 6 inches, the radius is half of that, which is 3 inches. So the area of each circular base is 3.14 * (3^2) = 28.26 square inches.
Adding the area of the curved surface to the areas of the two bases gives a total surface area of 75.36 + 28.26 + 28.26 = 131.88 square inches.
Therefore, 131.88 square inches of paper will be needed for the label on the outside of the can.
