Don't get cared by the decimal, it's just a point. It means: divide by 10^n where n is the number of digits after the decimal. So in this case, 3.14 means 314 / 10^2 = 314 / 100 so you are actually doing this 314/100 x 4 = 314 x 1/100 x 4. Multiplication is commutative so you might as well do 4 x 314, then divide by 100. So you should get 1256 / 100. To divide by 100, recall what decimal means, it's simply 12.56 :D
Area of a circle = pi*r2 1256 m2 pi * r2 1256/pi = r2 sqrt(399.797) = r = 19.99 meters ==============Could call this 20 meters in radius.
The diameter of a circle whose circumference is 314 is about 1 (99.95).
