An empty cylindrical container of radius 7m and height 10m is covered by a conical cap of radius 10.5m and height 9m. Calculate the volume of the air trapped inside

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
