Question

the rainwater from a roof 22m*20m drains into a cylindrical vessel having diameter of base 2 m and height 3.5m . if the vessel is just full , find the rainfall in cm.

pls do this problem in simple method

Answer 1

vol of rain water on the roof =vol of tank

22*20*h=22/7*1*1*3.5

h=22*3.5/7*20*22

h=1/40m

h=2.5cm

Answer 2

Answer:

The height of the rainfall is 2.5 cm.

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

$l\times b\times h=\pi r^2h$

$22\times 20\times h=(3.14)(1)^2(3.5)$

$440\times h=10.99$

$h=\frac{10.99}{440}$

$h=0.024m$

1m=100 cm

0.024 m=2.49 cm

Approximately the height of the rainfall is 2.5 cm.
