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.
3cm x 3cm = 9 cm^(2(.
Given this area, the sides measure 52.92734 cm
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.
silicon solar cells of 2 sqcm produces 0.5V and power of 0.7W. So to get 20Volts 40 solar cells are to be connected in sieries.
