A) \[1496\,{{m}^{2}}\]
B) \[1450\,{{m}^{2}}\]
C) \[1576\,{{m}^{2}}~\]
D) \[1694\,{{m}^{2}}\]
Correct Answer: D
Solution :
\[r=35\text{ }m;\text{ }R=35+7=42\text{ }m\] Area of circular path \[=\pi (R+r)\,(R-r)\] \[=\frac{22}{7}(42+35)\,(42-35)=1694\,{{m}^{2}}\]You need to login to perform this action.
