A charge distribution that is spherically symmetric but not uniform radially produces an electric field of magnitude $$E=5.0r^6\mathrm{N}/\mathrm{C}$$, directed radially outward from the center of the sphere. Here $$r$$ is the radial distance from that center. What is the volume density $$?$$ of the charge distribution for $$r=1.25\mathrm{m}$$ ? Number Units
