Hanky Panky has to make two oval boards: but it so happens that the
area, exclusive of hand-holes in the centre, and the circular piece, are
the same. To cut his stuff, on finding the centre of the circle, he
strikes a second circle, half the diameter of the first, with the same
centre. Then he cuts the whole into quarters, by means of two lines
drawn at right angles to each other, then cuts along the inner circle
(Fig. 92) and puts the pieces together, as in Figs. 93, 94.
