Answer :

GIVEN : radius of solid cylinder = “r”


height of solid cylinder “h” = 4.5cm


volume of the cylinder “V” = 62.37cm2


we take π =


TO FIND : radius of a solid cylinder = ?


PROCEDURE :


As we know, that


Volume of a cylinder “V” = π r2h


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


So we get, 62.37 = π ×(r)2×(4.5)


= π ×(r)2


13.86 = ×(r)2


r2 = = × 7 = 0.63 × 7 = 4.41cm2


r = √ 4.41 = 2.1cm


radius of the given cylinder = 2.1cm.
