A) 20 m
B) 50 m
C) 20 cm
D) 20.50 m
Correct Answer: D
Solution :
Circumference of the outer edge \[=66\times 200=13200\,cm\] \[\therefore \] \[r=\frac{13200\times 7}{2\times 22}=2100\,cm\] Radius of the pond = Radius of the outer edge ? width of the path \[=~\left( 2100-50 \right)=2050\,cm\] \[=\frac{2050}{100}m=20.50\,m\]You need to login to perform this action.
