Remember the area of a circle is
A = pi r^2
Surface area of a sphere is
S.A. = 4 pi r^2
The surface area of a circle can be found using the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius and multiply it by π to calculate the surface area.

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
it is still surface area
surface area/ volume. wider range of surface area to volume is better for cells.

The total surface area! The total surface area! The total surface area! The total surface area!
It should be relatively easy to find the surface area of a box when you are given the surface area.
You can increase surface area by spreading the object
It depends on the surface area of what!
To obtain the ratio of surface area to volume, divide the surface area by the volume.

the surface of the moon is 0.074 of earth's surface area
It is the area of the exposed surface. So if you take a cube, the surface area is the sum of the areas of each of the 6 faces. They are all the same in the case of a cube. In general, add up the surface area of each exposed surface and this is the total surface area.
