-
- r will be 10/2=5
and h=15
so ans= pi*125 - 11 years agoHelpfull: Yes(17) No(3)
- h=12
r=15
v=225pie - 11 years agoHelpfull: Yes(4) No(6)
- For cuboid volume=l*b*h=12*10*15
For cone volume=(1/3)*pi*r^2*h=(1/3)*pi*5^2*15=125pi - 11 years agoHelpfull: Yes(4) No(0)
- 225pie was the answer

- 125pi is the answer..
for eg:- take l=10,b=12,h=15
now for the base of cone..we can take diameter as 10,not 12 because the the base of cone is circle it will take a single parameter,we cant take 12 here coz,the length is 10 and there base will get extended out of the cuboid,hence take diameter as 10. - 9 years agoHelpfull: Yes(0) No(0)
