Actually, if it's linear growth, then the change ratio in
5 years implies having to go out 93 miles - not 100.
Just thought I'd try and cheer you up.
PH.
Calculation: change in last 5 years is
Pi x 75 x 75
- Pi x 50 x 50
= Pi x 3125 sq mi.
This means in another 5 years the boundary is defined by
Pi x 75 x 75 + Pi x 3125
= Pi x 8750
= Pi x 93 x 93
