22×20×h=4/5×(22/7)×1×1×7/2
h=1/50 (cm)
h=2cm
22×20×h=4/5×(22/7)×1×1×7/2

Answer:
Step-by-step explanation:
Given : The rainwater from a roof 22m*20m drains into a cylindrical vessel having diameter of base 2 m and height 3.5m .
To find : if the vessel is just full, the rainfall in cm?
Solution :
Diameter = 2 m
Radius = 1 m
Volume of rain water on the roof = Volume of tank
1m=100 cm
0.024 m=2.49 cm
Approximately the height of the rainfall is 2.5 cm.
