Question

How many iron balls each of radius 1cm can be made from a sphere of radius 8 cm
? ​

Answer 1

Answer:

512 iron balls can be made

Step-by-step explanation:

volume of larger sphere = nu of balls × volume of balls

radius of larger sphere = 8cm

radius of smaller sphere = 1 cm

$\frac{4}{3} \pi {r1}^{3} = x \times \frac{4}{3} \pi {r2}^{3} \\ {r1}^{3} = x \times {r2}^{3} \\ {8}^{3} = x \times {1}^{3} \\ x = {8}^{3} \\ x = 512$

512 iron balls can be made
