Question

14. The rainwater harvested on a roof 35 m 20 m is collected in a cylindrical tank with diameter 14 m and
height 5 m. If the tank is completely filled, find the height of rainwater on the roof.
​

Answer 1

Answer:

1.1 m

Step-by-step explanation:

volume of cylinder= pi x $r^{2}$x h

= 22/7 x 7 x 7 x5

= 22 x 7 x 5

= 2 x 11 x 7 x 5

= 770

volume of rooftop = l x b x h

770 = 35 x 20 x h

770= 700 x h

770/700= h

1.1 m =h
