Concrete sections for a new building have the dimensions (in meters) and shape shown in the figure.

y=1/3√(5+x) on interval (-5.5,0)
y=1/3√(5-x) on interval (0,5.5)
Width of 2m

(a) Find the area (in m2) of the face of the section superimposed on the rectangular coordinate system. (Round your answer to three decimal places.)


(b) Find the volume (in m³) of concrete in one of the sections by multiplying area in part (a) by 2 meters. (Round your answer to three decimal places.)

(c) One cubic meter of concrete weighs 5,000 pounds. Find the weight (in lb) of the section. (Round your answer to the nearest whole number.)
