Question

Find the ratio of surface area and volume of sphere.

Answer 1

For a sphere, surface area is S= 4*Pi*R*R, where R is the radius of thesphere and Pi is 3.1415... The volume of a sphere is V= 4*Pi*R*R*R/3. So for a sphere, the ratio of surface area tovolume is given by: S/V = 3/R.

Answer 2

hlo mate,

you can see on pic

To find the ratio of the volume of two spheres, we have to find their volumesfirst. Given that, ratio of the diameter of two spheres is 1:2. So let us assume d1 as 'x' and d2 as '2x'. Now divide (3) by (4), we get 1/8.
