Shanta runs an industry in a shed which is int he shape of a cuboid surmounted by a half cylinder (see Figure ) . If the base of the shed is of dimension ` 7 m xx 15` m, and the height of the cuboidal portion is 8 m find the volume of air that the shed can hold

Further, suppose the machinery int he shed occupies a total space of 300 `m^(3)` and there are 20 workers, each of whom occupy about ` 0 . 0 8 m^(3)` space on an average . The how much air is in the shed ? (Take ` pi =(22)/(7)` )
