If the radius of a circle is increased by 30% then the area is increased by: Choose the correct choice from the following answers.
A) 44%	B) 69%	C) 144%	D) 40%	E) None of the above
initially A=pi*r2   now R2=130/100r   then area=Pi*(130R/100)2   area=169R/100   that is area increases from 100 to 169=increase in area=69%   ANSWER:69%
<result>B</result>
