What is the surface area of a Coke can? (The Coke can is cylindrical, has a base of
2.5 inches in diameter, and is 4.8 inches long.)
The surface area of a cylinder is
A=2 x PI x R x H + 2 x pi x R^{2}
This is intuitive because the first term is the surface area
of the side of the can while the second term is the surface of both the bottom
and top of the can.
Will convert dimensions of can to millimeters by noting that
1inch is 25.4 millimeters.
The radius of the can is half the diameter or 1.25.
The radius of the can is half the diameter or 1.25.
The calculations are presented below.
