Ans. Let radius of the base and height of the cone be ‘r’ & ‘h’ respectively.

Then volume of cone = πr2h/3 For cylinder, radius is reduced by 4 times = r/4 And,  height is increased by 8 folds = 8h Volume of cylinder = πR2H = π(r/4)2 (8h) = (16/8)πr2h = πr2h/2 Ratio of volume of cone to volume of cylinder = (πr2h/3) : (πr2h/2) Or, Ratio = 2 : 3.

Radon gas is a source of natural groundwater pollution.

Garbage burning is common in rural areas, but it poses health concerns and hazards to the environment. It especially affects people with sensitive respiratory systems, as well as children and the elderly.

Benefits ::

• It produces methane that can be used like natural gas.
