Answer:

The water level rises in the reservoir is 13.6 cm/h.  

Step-by-step explanation:

Given : A cylindrical reservoir is 14m in diameter. Water is poured into it at the rate of 350 l/m.

To find : The rate in cm/hr at which the water level rises in the reservoir.

Solution :

A cylindrical reservoir is 14m in diameter.

Radius of the cylinder is 7 m.

The area of the cylinder is

A=πr²

A=(22/7)*7*7

A=154 meter square

1m³=1000 l

1 l=1/1000 m³

350 l=350/1000 m³

350 l=0.35 m³

Volume of the cylinder is

V=A × h

0.35=154 × h

0.35=154 × h

h=0.0022 m

1 hour = 60 minute,

h=0.0022*60=  0.136 m/h

1 m=100cm

h=0.136*100=13.6 cm/h

Therefore, The water level rises in the reservoir is 13.6 cm/h.
