After an election, the newly constituted Geocity planning office is exploring the use of hollow cylinders for water towers, and have built a model in their office. The model is hollow, open (on top) right circular cylinder (with negligibly thin walls ), as shown in the figure below. An intelligent bug is sitting at the point A in the figure on the outside of the cylinder, and a drop of honey is accidentally dropped at point B (diametrically opposite to the bug, but inside the cylinder, and at a different distance from the top) The bug crawls to the honey on the outside and the inside of the cylinder by the shortest path. If the circumference of the top of the cylinder is 78 cm, d=27 cm, and h=53 cm, then what is the distance (in cm) crawled by the bug before reaching the honey? The answer is rounded to he nearest integer

• 78/2+27+53=119

• how can you answer without diagram @ MUSHKAN

• if Bug is sitting at the top corner of the hollow cylinder:
  53(height)+78/2(half circumfarence)

• make an triangle where base is half of circumference and height is difference in height of bug and honey and find hypotenuse
  sqrt( (39)^2 + (26)^2 ) = 47(approx)
