a) length of mean turns = 3.14 * (inside diameter of coil + depth of windings)
b) length of mean turns = 3.14 / (inside diameter of coil + depth of windings)
c) length of mean turns = 3.14 * (inside diameter of coil * depth of windings)
d) length of mean turns = 3.14 + (inside diameter of coil + depth of windings)
