If the radius of a circle is increased by 20% then the area is increased by:
Choose the correct choice from the following:
A) 44% B) 120% C) 144% D) 40% E) None of the above
initially 44%=pi*r2   now R2=120/100r   then area=Pi*(120R/100)2   area=144R/100   that is area increases from 100 to 144=increase in area=44%   44%NSWER:44%
