Question

How many balls each radius 2cm can be made by melting a big ball whose radius is 8cm

Answer 1

Hey

Radius of larger ball = 8 cm

So ,

Volume of larger ball = 4/3 * pie * ( 8) ³ cm³

And ,

Radius of smaller ball = 2 cm

Volume of smaller ball = 4/3 * pie * ( 2 ) ³ cm³ .

Let the number of mmaller balls be x .


A / q ,

x * 4/3 * pie * ( 2 ) ³ = 4/3 * pie * ( 8 ) ³

=> x = 4 * 4 * 4

=> x = 64 .

Required number of balls = 64 .

thanks :)

Answer 2

64 balls can be made from it
