Height of cylinder = 20 cm
Volume of cylinder = 3080 cm^3
=> pi *r^2 *h = 3080
=> 22*20*r^2 /7 = 3080
=> r^2 = 3080 * 7 / 20 * 22
=> r^2 = 154*7/22
=> r^2 = 7*7
r= 7 cm
Radius of cylinder = 7cm
Volume of cylinder = 3080 cm^3
=> pi *r^2 *h = 3080
=> 22*20*r^2 /7 = 3080
=> r^2 = 3080 * 7 / 20 * 22
=> r^2 = 154*7/22
=> r^2 = 7*7
r= 7 cm
Radius of cylinder = 7cm
