If the radius of a circle is increased by 40% then the area is increased by:
Choose the correct choice from the following:  A) 44%  B) 120%  C) 96%  D) 40%  E) None of the above
initially A=pi*r2   now R2=140/100r   then area=Pi*(140R/100)2   area=196R/100   that is area increases from 100 to 196=increase in area=96%   ANSWER:96%
