Answer:

The surface area to volume ratio is #"1/3r":1#, where #r# is the radius of the sphere.

Explanation:

The formula for the volume of a sphere is

#V = 4/3πr^3#, where #r# is the radius of the sphere.

The formula for the area of a sphere is.

#A = 4πr^2 #

So the surface area to volume ratio is

#"SA"/"V" = ((cancel(4π)r^2)/3)/(cancel("4π")r^3) = 1/(3r)#
