GIVEN :-
cylinder :
- hieght ( h1 ) = 32 cm
- radius ( r1 ) = 18 cm
cone :
- height ( h2 ) = 24 cm
TO FIND :-
- radius ( r2 ) and slant hieght ( s ) of heap ( cone )
SOLUTION :-
since in cylinder bucket is emptied to make a colonial heap
volume of cylinder = volume of cone
now volume of cylinder :-
hieght ( h1 ) = 32 cm
radius ( r1 ) = 18 cm
we know the formula that volume of cylinder :-
now volume of cylinder :-
height ( h2 ) = 24 cm
let radius be r cm
and slant hieght be l cm
we know the formula of volume of cone :-
now volume of cylinder = volume of cone hence ,
now we have to find slant hieght :-
HENCE,
