Question

the radius of a glass sphere is 5 cm how many spheres of radius 5mm can be made from it
​

Answer 1

Answer:

500 spheres of radius 5mm can be made

Answer 2

Number of spheres can be formed is 1000 .

Given :

The radius of a glass sphere is , R = 5 cm .

We need to find how many spheres of radius 5 mm can be made from it .

So , r = 5 mm = 0.5 cm .

Now , number of spheres formed :

$n=\dfrac{Volume \ of \ glass\ sphere}{Volume \ of \ sphere\ formed}\\\\n=\dfrac{\dfrac{4\pi R^3}{3}}{\dfrac{4\pi r^3}{3}}\\\\\\n=\dfrac{R^3}{r^3}\\\\n=\dfrac{5^3}{0.5^3}\\\\n=1000$

Therefore , number of spheres can be formed is 1000 .
