Answer:
r= 14 m
Step-by-step explanation:
volume(cuboidal tank) = volume(cylindrical tank)
lbh1 = πr^2h
11 × 7 × 4 = 22/7 × r^2 × 2
r^2 = 4 × 49
r= 2×7
r= 14 m

l=11m,b=7m,h=4m(Given)
VOLUME OF CUBOIDAL WATER TANK=LBH
11×7×4=308m^3
Capacity of the tank=Volume of cylindrical tank
H=2m,Volume of cylinder=308cm cube
308=22÷7×r square ×2
r suare=49
Radius=7cm
