Question

64 solid metellic spheres each of radius 0.15 cm are melted to form a single bigger sphere . find the radius of bigger sphere?

Answer 1

Answer:

0.6 cm

Step-by-step explanation:

volume of sphere=4/3*pi*(r^3)

vol.=4/3*22/7*0.00375

vol=0.014

total volume=0.014*64=0.896

radius of greater cube=0.6

Answer 2

Answer:

Step-by-step explanation:

Since they're being melted we need to find the volume.

Voleme of one tiny sphere

=4/3pie r^3

=4/3×22/7×0.15×0.15×0.15

=0.099/7

=0.014

Volume of 64 such spheres or One big sphere

=0.014×64

=0.896

Radius of sphere

0.896=4/3 pie r^3

0.896=4/3×22/7×r^3

0.896×3/4×7/22 = r^3

4.704/22= r^3

0.216(approx.) =r^3

0.6=r^3
