1. The ratio between curved surface area and total surface area of a right angle circular cylinder is 2:3 find ratio between height and radius of cylinder.

2 . A shotput is a metallic sphere of radius 4.2 cm. If density of metal is 10 gram per cm sq , find mass of shotput.

3. A tailor has a piece of canvas whose area is 552 M sq.he uses it to make a conical tent with base radius 7cm.Assuming that all stitching margin and wastage incurred while cutting,amounts to approximately 2 M sq. Find volume of tent that can be made with it (Also write values).

4. A conical vessel with radius 20 cm and height 30 cm is full of water. The water of the vessel is transferred to cylindrical vessel of radius 8 cm. Find up to what height will the cylindrical vessel fill.

1.curved surface area of a right angle cylinder =2 total surface area of a right angular cylinder= csa/tsa=2/3 pi x r on both the sides get cancelled 2h/h+r=2/3 6h=2h+2r 3h=2r h/r=3/2 2.Area of sphere=4 x pi x r x r 4 x 22/7*4.2*4.2 221.76sq cm mass=221.76*10=2217.6g 4.volume of cone=1/3*pi*r²*h volume of cylinder=pi*r²*h ATQ volume of cone =volume of cylinder where the height of cylinder is not given 1/3*pi*r²*h=pi*r²*h pi on both ides get cancelled 1/3*20*20*30=64*h 4000=64*h 4000/64=h 62.5=h 3.csa of conical tent =552m² but 2m² is cut after stiching so the remaining area is 550m² csa of cone =pi*r*l 550=22/7*7*h 550*7/22*7=h 25m=h
