               2  Work out:  i the circumference       ii   the area of these circles.
                  a  radius = 4 cm                  b diameter = 12 cm
                  Use π = 3.14.
                  Round your answers correct to 1 d.p.
               3  Show how you would check your answers to question 1, using a single number instead of π.
