B. 132 units

C. 616 units

D. Cannot be determined

E. None of these

Answer: Option A

Solution(By Examveda Team)

$$\eqalign{ & \pi {R^2} = 7 \times \left( {2\pi R} \right) \cr & \Rightarrow R = 14 \cr & \therefore {\text{ Circumference :}} \cr & {\text{= }}\left( {2 \times \frac{{22}}{7} \times 14} \right)\text{units} \cr & = 88\,\text{units} \cr} $$
