# 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.
