Answer:

Step-by-step explanation:
= Surface area of base = 5 square meters
Volume of water in tank = 70 cubic meters
The rate at which the volume is reducing is

Integrating from
to 

Volume of water remaining in the tank is 
Suface area of base
depth = Volume

The depth of the water remaining in the tank is
.
The area of a circle of radius r is pi*r^2
Hence here the area is A=5^2*pi=25pi~78.5 square inches
