This alphametic has been created in honour of that
remarkable number p, which is exactly
equal to the ratio of the circumference of a circle to its
diameter. As usual, each of the eight letters of the alphabet used
conceals a specific digit.
Ancient Greek mathematicians paid a lot of
attention to p, and Archimedes showed
that its precise numerical value lies between 3 10/71 and 3 10/70.
And of course there is pr2 =
the area of a circle.
Your task here is to deduce the actual sum involved:
