If the radius of a circle is increased by 60% then the area is increased by:
Choose the correct answer.
A) 44%	B) 120%	C) 156%	D) 40%	E) None of the above
initially A=pi*r2   now R2=160/100r   then area=Pi*(160R/100)2   area=256R/100   that is area increases from 100 to 256=increase in area=156%   ANSWER:156%
<result>C</result>
