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

Capacity of tank = volume of cylinder
πr^2h = 3080
22/7 x 20 x r^2 = 3080
r^2 = 3080 x 7/440
r^2 = 7 x 7
r = 7cm
Diameter = 2r = 2 x 7 = 14cm
πr^2h = 3080
22/7 x 20 x r^2 = 3080
r^2 = 3080 x 7/440
r^2 = 7 x 7
r = 7cm
Diameter = 2r = 2 x 7 = 14cm
