i donot understand your question
I think I see two columns hidden in there
The formula to use on all of these is d = 2r.
Generally it is better to state the known information first, then calculate what is unknown.
1. r = 21cm
d = 2x21cm = 42cm
2. r = 26.3dm
d = 2x26.3dm = 52.6dm
3. r = 14m
d = 2x14m = 28m
4. d = 18.4ft
r = d/2 = 18.4/2 ft = 9.2ft
5. d = 4 3/4 in
r = d/2 = (4 3/4)/2 in = 2 3/8 in
