"What is ..." is a pretty open question with lots of different answers that won't be helpful. If you're seeking a specific answer, it would be nice to see the question say what answer you seek.
Area = pi * r^2
Area = pi * 12^2 = 452.39 square units
Circumference = 2(pi) * r
2 * pi * 12 = 75.40 units
