None. A centimetre is a measure of distance while a sq cm is a measure of area. The two measure different things and it makes no sense to try to convert from one to the other.
Given this area, the sides measure 52.92734 cm
100 sqcm
There are 2.54cm per inch. So this being a square function multiple 2.54x2.54=6.4516 take total sqcm and divide by 6.4516. Example 4"x4"=16"sq (4x2.54=10.16) x (4x2.54=10.16) 10.16x10.16=103.2256 sqcm 103.2256sqcm/6.4516=16"sq
The formula for area of a circle is pi*r*r. If the circle is 4 cm across then the radius is 2 cm. pi times 2 times 2 is 4pi. Many people use 3.14 as pi. 4 time 3.14 is 12.56 sqcm.
