After Mt.St.Helens erupted in 1980, it was found that ash was spread in decreasing density as a function of distance r from the center of the crater.Say that the density $\rho$ of ash at a distance r (meters)from the center of the crater is given by $\rho(r)=\frac{2000}{1+r^{2}}$ kg/m².Find the total amount of ash within 1400 meters of the center of the crater.Round to the nearest whole number and give your answer in kg.
