9.30%, nearly.

The mantle extends from about 35 km to about 2890 km.

The volume of this spherical shell is

#4/3pi(2890^3-35^3) km^3#

#=1.011 X 10^11 km^3#, nearly.

The volume of the Earth is

#4/3pi6378^3 km^3#

#=1.087 X 10^12 km^3#, nearly.

So, the perventage of mantle volume is

#(1.011 X 10^11)( 1.087 X 10^12) X 100#

#=9.30#
