A) 236
B) 237
C) 2355
D) 238
Correct Answer: C
Solution :
Length of rope \[=20\,m\] Radius\[=20\,m\] \[\therefore \] Area of the field in which the horse can now graze \[=\frac{1}{4}\times \pi \times {{(20)}^{2}}=314\,{{m}^{2}}\] \[\therefore \] Increase in grazing area\[=314-78.5\] \[=235.5\,{{m}^{2}}.\]You need to login to perform this action.
