Circle-Calculator-Program

Type: Bro Code course project Date: Sept 2026 Concepts: double, const, math.h, pow(), formatted %.2lf output

What it does

Takes a radius as input and calculates a sphere's area, surface area, and volume.

What I learned

math.h functions like pow() may need the math library linked at compile time with -lm, or the compiler reports an "undefined reference" error on some systems. I also learned math.h provides an M_PI constant that's more precise than defining PI by hand.
