4) The Geocity planning office is exploring the use of cones for water tower, and have built a model in their office. The model is a hollow, open (no tap) right circular cone, as shown in the figure below. An intelligent mathematical bug is sitting at the point A in the figure, and a drop of honey is accidentally dropped at point B (diametrically opposite the bug, at the top of the cone.)
The bug crawls to the honey on the surface of the cone by the shortest path.
If L = 336 cm, r = 168 cm, and h = 98 cm then what is the distance (in cm) crawled by the bug before reaching the honey? (Round the answer to one decimal)
Use  = 3.14, = 1.41, and = 1.73

Read Solution (Total 5)

figure will be an inverted cone having diameter 336 and circumfernce x=2*pi*r , pi*r=x/2 , x=54.4 , ans = 54.4/2=28.2
