Thanks Hi Douglas,
This follow from the wonderful property of circles. No matter how large or small a circle you have, if you divide the distance around (the circumference) by the distance across (the diameter) the answer is always p. That is The number is approximately 3.1416 and hence if the circumference is 25000 miles as in your example then ^{25000}/_{diameter} = and the diameter is then ^{25000}/_{} which is approximately 7958 miles. Cheers,Penny
