HERE IT IS GIVEN........
Radius and height of the cylindrical
are in the ratio of 3:7 and its volume
is 1584 cm cu find radius
_____________________
let x is included in the ratio
so.....
height = 7x and
radius = 3x
now.......
volume of the cylinder
=) 1584=22/7×r^2×h
=)1584= 22/7× 9X^2×7X
=)1584=198X^3
=) 1584/198=X^3
=) 8=X^3
=) 2=X
=) hence......
radius will be 6 cm
