    if r is 12 what is r^2 (r squared = r times r) ( = 12 times 12)

    if oyu think maths notation is "gibrash" then I suggest you concentrate on your English (it's gibberish) You are evidently studying areas and circles If you cannot work out a square of a number then you cannot do this subject. Find out how to do 'squares' and then try to work out pi times 12 squared
