A) 88 m
B) 80 m
C) 44 m
D) 72 m
Correct Answer: D
Solution :
If radius = r metre, then \[\frac{\pi {{r}^{2}}}{2}=308\] \[\Rightarrow \]\[\frac{22}{7}{{r}^{2}}=616\] \[\Rightarrow \]\[{{r}^{2}}=\frac{616\times 7}{22}=196\] \[\Rightarrow \]\[r=\sqrt{196}=14\] metreYou need to login to perform this action.
