The radius and he

Answer :

GIVEN : radius of solid cylinder = “r”


height of solid cylinder = “h”


=


volume of the cylinder “V” = 4400cm2


we take π =


TO FIND : radius of a solid cylinder = ?


PROCEDURE :


As we know, that


Volume of a cylinder “V” = π r2h


Also, we have, =


= h = r ×


So we now put the values of V and h in the above formula for V,


So we get, 4400 = π ×(r)2×( r × )


4400 = × r3×


4400 × × = r3


200 × 5 = r3


1000 = r3


So, r = 1000 = 10


radius of the given cylinder = 10cm.
