Directions: Q. 1 to 5 |
A farmer has a rectangular field of length 60 m and breadth 30 m. By the farmer a pit of diameter 14 m is dug 12 m deep to make a well. The earth taken out is spread in the field. |
Based on the above information, answer the following questions. |
A) \[1460{{m}^{3}}\]
B) \[1462{{m}^{3}}\]
C) \[1848{{m}^{3}}\]
D) \[1850{{m}^{3}}\]
Correct Answer: C
Solution :
Volume of the earth taken out can be given by the volume of the pit. Given, \[r=\frac{14}{2}=7m\] Volume \[=\pi \times {{\left( 7 \right)}^{2}}\times 12\] \[=\pi \times 49\times 12\] \[=\frac{22}{7}\times 7\times 7\times 12\] \[=1848\,{{m}^{3}}\]You need to login to perform this action.
