Theory. Cylinder Area

Cylinder

is a three-dimensional geometric shape that bounded by cylindrical surface and two parallel planes (the bases) that cross it. The cylinder is called the right circular cylinder, if its base is a circle. The distance between the bases is the height of the cylinder.

Area formula of the cylinder side

A = 2 π R h

The formula for the surface area of a cylinder

A = 2 π R h + 2 π R ^{2} = 2 π R(R + h)

where A - area,
R - the radius of the top,
h - the height of the cylinder,
π = 3.141592.
