5. A hollow pipe has circumference 14 cm. A bug is on its wall at a distance of 48 cm from top. A drop of honey is on the wall at 24 cm from top but diametrically opposite to bug. Find the shortest distance bug has to travel to reach honey.
a) 25 cm b) 39 cm c) 21 cm d) 24 cm

• Total Vertical Distance bug has to through = 24 cm
  Circumference of pipe= 14 cm
  Since bug has to move to diametrically opposite side, it has to cover half of the circumference = 14/2 = 7 cm
  
  SO by Pythagoras, diagonal distance would be = sqrt(7^2+24^2) = sqrt(625) = 25 cm

• it will become rectangle of 7X24. solve using pythagoras. answer is 25

• piyush can u plz explain it in detail? what is 7? circumfrence is given 14

• circumference is given, not diameter....

• the diagram can be seen as..
  honey at 24 | | bee at 48

  we have to find out the diagonal distance. here in this trapezium. it is opp so altitude is 7. parallel side is 48 & 24. the hypo comes out to be sqrrt(24^2 + 7^2) = 25

• dummy......ques.....taht is nt diameter dude

• the bug is at the hight of 48cm ad the honey is at 24 cm
  the difference in hight is 24 cm
  and the circumference is give as 14 but the bug must only travel half of the pipe so the distance is 7 cm
  now to find the shortest path is,
  it forms a right angler triangle.
  so,x^2=7^2+24^2
  therefore, x=25 cm

• i think its 24 because shortest distance is straight line...

• i think answer should be 27.8

  diagonal distance can be find easily ans is 25
• 11 years agoHelpfull: Yes(1) No(0)
• 24
  because the drop is place at the half of the distance from the bug

• answer is 24
  first we have to calulate the diameter which is 49/11
  then by Pythagoras,sqrt root( 24^2-(49/11)^2)=23.58 from top
  then 48-23.58=24.42 ,i.e. approx 24

• ans must be 25
• 8 years agoHelpfull: Yes(0) No(0)
• Difference if heights of honey and bug is 24 answer will obviously be greater than 24 thus 25 is the answer
