$7,1$ point

An insulating thick spherical shell of inner radius $3\mathrm{.}2cm$ and outer radius $7\mathrm{.}4cm$ has uniform charge density $63\mathrm{.}7\frac{nC}{m^3}.$ What is the magnitude of the electric field $11\mathrm{.}1cm$ away from the center of the spherical shell? $($please provide your answer N$/$C to $2$ decimal places$)$
