Question

The radius and the height of a cylinder are in the ratio 3:2 and its volumne is 19,404 cm© find its radius and height

Answer 1

Answer:

Step-by-step explanation:

solution⇒

given⇒ r: h =3:2

⇒if radius (r) =3x cm

   hight  (h)   = 2x

volume of cylinder =19404$cm^{3}$

as we know the formula

volume of the cylinder= π $r^{2}$ xh

         19404   = 22/7 x 3x  x 3x x 2x

         19404    =22 /7 x 18 $x^{3}$

$\frac{19404 x 7 }{22 x 18}$=$x^{3}$

$x^{3}$ =343

x=7

radius = 2x =2 x 7=14

hight   =3x  =3 x 7=21
