The geocity planning office is exploring the use of cones for water towers, and has built a model in their office. The model is a hollow, open (no top) right circular cone. An intelligent mathematical bug is sitting at the point A (at top), and a drop of honey is accidentally dropped at point B (on the opposite side of the cone, at the top). The bug crawls to the honey on the surface of the cone by the shortest path. If R=270 cm (slant height) and r=90 cm (radius), then what is the distance (in cm) crawled bye the bug before reaching the honey?
A)135 B)270 C)282.6 D)141.3

• Answer:C
  
  Circumference of the circular cone is 2*pi*r
  Bug crawls from point A to point B which is opposite to each other.
  so, the shortest path for the bug to crawl to the point B form point A = Half of the circumference of the circular cone.
  therefore,pi*r=3.14*90=>282.6.

• tricky question just do it by making a original cone. and then you find the right answer. b) 270

• bug crawls half of the circumference of the circle of cone.

• It will be b)270 because shortest distance is nothing but the slant height of the cone.

• A to B= (2*PIE*R)/2= PIE*R=22/7*90=282.85~= 282.6=ANS
