Answer:

Step-by-step explanation:

Given

Volume of Cylinder (V)= 480 cm

height (h) = 30 cm

radius (r) = ?

WE KNOW THAT WE HAVE FORMULA

Volume (V) = [tex]\pi r^{2} h[/tex]

           480 = 3.14 * r^2 *30

            480 = 94.2 r^2

             480/94.2 = r^2

               r^2 = 5.1

                 r =[tex]\sqrt{5.1}[/tex]

Therefore r = 2.3 cm
