Multi-Pi Multi-Cache

This is a fairly short 3 stage multi.  Brush up on your Pi skills! You will need them to get to the second and final stages.  The test begins at the listed coordinates where you will have to solve 2 simple π calculations. From Stage 2, you will have to solve 2 harder but still simple calculations to get to the final. Pi = 3.14159 in all calculations and round up or down to the nearest whole number.

Consider these two basic mathematical equations:

C = 2πr

A = πr²

C = Circumference, R = Radius, D = Diameter (R*2), and A = Area.

Good luck and remember to have fun!
