Question

how many spherical balls each of radius 1 cm can be made from a solid sphere of lead of radius 4cm​

Answer 1

Answer:64 balls

Step-by-step explanation: volume of sphere having radius 4 cm= volume of sphere having radius 1cm*n

Therefore 4/3π(4)cube=4/3π(1

)Cube*n

4/3πgets cancelled on both sides

Then we have n= 4cube=64
