answered-by-expert Expert Answer
Vol of air = Vol of cylinder + Vol of cone Now, Volume of cylindrical container = pi x r x r x h =(22/7)x7x7x10 =1540mcube Volume of conical cap = (1/3) x pi x r x r x h = (1/3) x (22/7)x10.5x10.5x9 = 1039.5mcube Vol of the air trapped inside = 1540 + 1039.5 = 2579.5mcube
