- let third side is x.
therefore,
by pythagores theorem,
x^2 + (20)^2 = (29)^2
hence, x=21.
Ans. is 21 - 10 years agoHelpfull: Yes(3) No(4)

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
