Answer:
Correct Answer:
D) 1 : 4
Description for Correct answer:
Volume of cylinder = πr21h
Volume of sphere = 43πr32
Number of spheres = 48
Therefore, Volume of cylinderVolume of sphere=πr21h43πr32
=> πr21h43πr32=48
=> (Because,r1=h)
=> 34(r1r2)3=48
=> (r1r2)3=48×43
(r1r2)3=64
=> r1r2=4
=> r1r2=14
