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
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

Cylinder=πr²h
3080=22/7×r²×20
3080×7/440=r²
49=r²
7cm=r
d=2r
d=2×7
d=14cm
3080=22/7×r²×20
3080×7/440=r²
49=r²
7cm=r
d=2r
d=2×7
d=14cm
