Question 137
A pole broke at a height of $4.2~\mathrm{m}$ above the ground at an angle of $79^\circ$ (see the figure).
What was the height of the pole before it broke? How many $\mathrm{dm}^3$ of wood does the lower part of the pole, up to the break, contain, if the diameter of the pole is $60~\mathrm{cm}$?
