The roof of a castle tower is shaped like a cone. The base of the cone is 24 m across and the height is
16 m. The slant height of the roof, which is unknown, is the hypotenuse of the right triangle formed
with the radius and the height of the cone.
(a) Sketch the roof of the castle tower. Label the known lengths as described and label the
unknown length as x.
(b) What is the slant height of the roof?
