a cylinder can of coca has the dimensions of base 7in and height 5 inches. what is the approximate surface area available for the label?
A = 2 * pi * r * h

can you pleae explain how to do this?
Is 7 inches the radius, diameter or circumference of the base?
7 inches is across the top of the can and 5 goes up and down.
Multiply:
2 * 3.14 * 3.5 * 5 = ?
To find the approximate surface area available for the label on a cylinder, we need to consider the curved surface area of the cylinder.
The curved surface area of a cylinder is given by the formula: A = 2πrh, where "A" is the surface area, "π" is Pi (approximately 3.14159), "r" is the radius of the base, and "h" is the height of the cylinder.
In this case, the radius (r) of the base of the can is 7 inches and the height (h) is 5 inches.
Substituting the values into the formula, we have:
A = 2π(7)(5)
Now we can calculate the approximate surface area available for the label:
A ≈ 2(3.14159)(7)(5)
A ≈ 219.91164 square inches
Therefore, the approximate surface area available for the label on the cylinder can of Coca-Cola is approximately 219.91164 square inches.
