Question

calculate the length of the pipe.
10. The rain water from a roof 22 m x 20 m drain into a conical vessel having
diameter of base as 2 m and height 3.5 m. If the vessel is just full, then find the
rainfall​

Answer 1

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.
