The magnitude of the area of a circle is seven times that of its circumference. What is the circumference (in units) of the circle ?
A
88 units
B
132 units
C
616 units
D
Cannot be determined
E
None of these
Correct Answer: 88 units
$$\eqalign{ & \pi {R^2} = 7 \times \left( {2\pi R} \right) \cr & \Rightarrow R = 14 \cr & \therefore {\text{ Circumference :}} \cr & {\text{= }}\left( {2 \times \frac{{22}}{7} \times 14} \right)\text{units} \cr & = 88\,\text{units} \cr} $$
