Question

Ramesh threw a party on the recovery of his injured friend from the accident ramesh served him and 5 other friends with chilled juice which was cylindrically shaped cans of radius 4.2 cm and height 15 cm find the total volume of juice they drink and total surface area of 7 juice cans which value is depicted by ramesh

Answer 1

radius of a cylindrical can = r
height = h
Volume = π r² h
Volume of 7 cans = volume of the juice drink
     = 7 * 22/7 * 4.2² * 15 cm = 5821.2 cm³

Total Surface area of a can = 2 π r (r + h)
Total surface area of 7 cans :  7* 2* 22/7 * 4.2 (4.2+15) = 3,54816 cm³ or cc
     = 3.54816 Litres

===
The value depicted by Ramesh is that we should always wish for the good and well being of our friends. We should share joy with our well wishers and close friends. Also showing our good concern to our friend, who is ill or recovering from illness, does good to that person. He/she would recover faster. For a person who is down with accident, this well wishing party gives a boost to recover better.
