The surface area is 4 pi r square and the volume is 4/3 pi r cube
The ratio of surface area to volume is 3 to r, so 3 to 10, which is eaqual to 30%

SOLUTION:
Surface area = 4 *22/7 *r2
= 3/r(4/3 * 22/7 * r3)
=3/r * VOLUME
Where r = 10 cm
So we have S= 3/10 V
=3/10 *100 % of V
= 30 % of V
So surface area is 30 % of Volume.

We know if r is the radius of the sphere
then it's surface area is 4*pi*r*r
and it's volume is (4*pi*r*r*r)/3
according to this formula
its surface area is 1256.64 cm sq.
and it's volume is 4188.79 cm cube
according to the numerical value we get that
the surface area is 30 % of the volume
that's it..
