Question

ashish is digging a pit of radius 2.8m and 3m depth. he is using os using a mud dug out from the pit to fill a vacant area pf land of dimension 8m × 2m. find the raised height of the vacant area.

Answer 1

Answer: The raised height of the vacant area is 4.62 m.

Step-by-step explanation:

Given that

Radius of the pit, r= 2.8 m

Depth of the pit, d= 3 m

The pit would be of cylindrical shape.

So, the volume of the pit would be given by

Volume of pit= pi*r^2*h

= 22/7*2.8^2*3

= 22/7*2.8*2.8*3

= 22*0.4*2.8*3

= 73.92 m^3

Since the mud dug out from the pit is used to fill a vacant area pf land,

volume of land to be filled= The volume of the pit

Area of the land*raised height= 73.92

8x2*raised height= 73.92  ( since area of land= 8x2)

raised height= 73.92/16= 4.62 m
