Answer :

GIVEN : radius of solid cylinder = “r”

height of solid cylinder = “h”

=

volume of the cylinder “V” = 4400cm^{2}

we take π =

TO FIND : radius of a solid cylinder = ?

PROCEDURE :

As we know, that

Volume of a cylinder “V” = π r^{2}h

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 = × r^{3}×

4400 × × = r^{3}

200 × 5 = r^{3}

1000 = r^{3}

So, r = ∛ 1000 = 10

∴ radius of the given cylinder = 10cm.
