Q Search
To find the surface area of the label, we need to find the surface area of the can and subtract the surface areas of the circular top and bottom.
The surface area of the can is given by the formula: 2πr(r+h), where r is the radius and h is the height.
Given that the diameter of the can is 6 inches, the radius is 6/2 = 3 inches.
Substituting the values into the formula, we get: 2π(3)(3+4) = 2π(3)(7) = 42π.
Now, let's find the surface area of the circular top and bottom of the can. The formula for the surface area of a circle is πr^2.
Substituting the radius into the formula, we get: π(3)^2 = 9π.
To find the surface area of the label, we subtract the surface areas of the circular top and bottom from the surface area of the can: 42π - 9π = 33π.
Since π is approximately 3.14, we can approximate the surface area of the label as 33(3.14) = 103.62 square inches.
Therefore, approximately 103.62 square inches of paper will be needed for the label on the outside of the can.
