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.
The label on the outside of the can will be a rectangle. The length of the rectangle will be the circumference of the circle formed by the can's diameter, and the width of the rectangle will be the height of the can.
The circumference of a circle is found using the formula: circumference = pi * diameter.
Given that the diameter of the can is 6 inches, we can calculate the circumference as follows:
circumference = pi * 6 = 3.14 * 6 = 18.84 inches.
Therefore, the length of the rectangle (which will be the same as the circumference) is 18.84 inches.
The width of the rectangle is given as 4 inches.
To find the area of a rectangle, we use the formula: area = length * width.
Therefore, the area of the label will be:
area = 18.84 * 4 = 75.36 square inches.
So, 75.36 square inches of paper will be needed for the label on the outside of the can.
