The formulas are as follows:area = PI * (radius) * (radius) orarea = PI * (diameter / 2) * (diameter / 2)radius = (diameter / 2) orradius = sqrt(area / PI)diameter = 2 * radius ordiameter = circumference / PIcircumference = PI * diameter orcircumference = PI * (radius * 2)sphere surface area = 4 * PI * (radius * radius)sphere volume = 4/3 * PI * (radius * radius * radius) ...

round cabinet, those formulas are finally coming in handy for something
