-
- Height of the cone = h = 7 cm
Radius of the cone = r = 5/2 mm = 2.5 mm = 0.25 cm
Volume of the cone = 1/3 π r2h = 1/3 * 22/7 * (0.25)2 * (7)
=11/24 cc = 11/24 * 10-3 ltr
11/24 * 10-3 ltr will write 330 words
=> 1 ltr will write 330*24*1000/11 = 720000 words
=> 3/5 th of litre will write 3/5 * (720000) = 432000 words - 12 years agoHelpfull: Yes(3) No(0)
