(b) Water flows from the cylindrical container along the pipe into the cone-shaped cups at a rate of 7.8 ml per second. Calculate the time taken to fill ONE of the empty cone-shaped cups. Give your answer correct to the nearest second. [The volume, \( V \), of a cone with radius \( r \) and height \( h \) is \( V=\frac{\pi}{3} \pi r^{2} h \).] (c) Determine the number of empty cone-shaped cups in (b) that can be completely filled from the cylindrical container.
