How many complete spheres of radius r/10 can you make by melting and re-moulding a sphere of raduis r?
Read Solution (Total 2)
-
- Vol of smaller sphere = (4/3)*pi* (r/10)^3
vol of larger sphere of rad r = 4/3)*pi* r^3
so no of smaller spheres = [4/3)*pi* r^3]/[(4/3)*pi* (r/10)^3] = 1000 - 13 years agoHelpfull: Yes(4) No(1)
- let r = 10
therefore smaller radii= 1
vol. of bigger sphere = 4/3*pi*(1000)
vol of smaller sphere = 4/3*pi*(1)
no. of spheres = (bigger/smaller)=1000 - 13 years agoHelpfull: Yes(1) No(0)
