h = 20 cm
Volume of cylinder = Capacity of tank
πr^2h = 3080
(22×20/7) × r^2 = 3080
r^2 = 3080×7/22×20
r^2 = 7×7
r = 7 cm
hence the diameter of the tank
= 2r = 2×7 = 14 cm
Volume of cylinder = Capacity of tank
πr^2h = 3080
(22×20/7) × r^2 = 3080
r^2 = 3080×7/22×20
r^2 = 7×7
r = 7 cm
hence the diameter of the tank
= 2r = 2×7 = 14 cm

Depth of tank = 20 cm
Volume of tank = 3080 cm^2
pi * r^2 *h = 3080
=> 22*20*r^2 /7 = 3080
=> r^2 = 3080*7/440
=> r^2 = 7*7
r = 7
Radius of cylinder = 7cm
Diameter of cylinder= 14 cm
Volume of tank = 3080 cm^2
pi * r^2 *h = 3080
=> 22*20*r^2 /7 = 3080
=> r^2 = 3080*7/440
=> r^2 = 7*7
r = 7
Radius of cylinder = 7cm
Diameter of cylinder= 14 cm
