How many spherical balls, each of radius 1cm, can be made from a solid sphere lead of radius 8cm
Answers
hey
gd evening
here is your answer
-----------------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------------
Volume of the spherical ball of radius 8 cm = 4/3π x 83c3
Also, volume of each smaller spherical ball of radius 1cm = 4/3π x 13cm3.
Let n be the number of smaller balls that can be made. Then, the volume of the larger ball is equal to the sum of all the volumes of n smaller balls.
Hence, 4/3π x n = 4/3π x 83
=> n = 83 = 512
Hence, the required number of balls = 512.

thanxx and be brainly..........
Answer:
Step-by-step explanation:
no. of balls =(volume of big sphere)/(volume of small sphere)
=(4/3πR^3)/(4/3πr3)
=(3^3)/(1^3)
=27/1
=27
hence,27balls are made from big sphere
