Question

For a spherical particle of radius r the volume to surface area ratio is

Answer 1

volume:surface area
4/3 pie r2 : 4 pie r2
4/3 pie r2= 4 pie r2
1/3= 1
1=3
1:3

Answer 2

hello users ....
solution:-
we know that ;
for a sphere of radius r
the volume = 4/3×π r³ cube unit
and
surface area = 4πr² square unit

Now,
the ratio of volume to the surface area is

=> volume of sphere / surface area of sphere

=> 4/3×πr³ / 4πr²
=> r/3

= r : 3 Answer
