Read Solution (Total 1)
-
- 2gr/cm^3 so weight = 900 Kg (900000 gms)
:: Volume taken out is 45000 cm^3
Volume of hemisphere is 2/3pie*r^2 ... which here is 140cm^3
So, no. of hemispheres is 450000/140 = 3214.28 = 3214
Ans: A) 3214 - 12 years agoHelpfull: Yes(15) No(3)

The British mathematician Lewis CaroII also loved to make up fantastic stories in which he embedded a number of clever puzzles and curious riddles. For example, his popular story, Alice in Wonderland, is about a young girl called Alice who dreams of a strange world where she meets several unusual characters including the Red Queen and the March Hare. In our story, after 4 years of time, Paul will be 3 times as old as Alice. Presently he is 6 times as old. How old is Paul now?
