The Surface Area of a Sphere = 4pi r 2
I believe this formula is the same for a nickel, as a nickel falls into the "circle" or "sphere" category.
Actually it is the formula 2B+Ch because the nickel is technically a cylinder that is really short so it uses the cylinder formula and NOT the sphere formula.
B is the area of the base or a face of the nickel. Doubling it counts for the other base and C is the circumference of the base. h is the height of the whole thing. A nickel's surface area is (2)(3.14)(1.052)+(3.14)(2.1)(0.15). Figure out the rest yourself.

First off, area is in square cm while distance is in cm. The radius of a nickel is 1.0605 cm, so using the famous formula pi x r2 for the area gives: 3.141593 x 1.06052 = 3.5332 cm2
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
To obtain the ratio of surface area to volume, divide the surface area by the volume.
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose
A nickel's value is not voided due to worn surface. It should still be worth 5 cents.
