The circumference of two circles is 88 metres and 220 metres respectively. What is the difference between the area of the larger circle and the smaller circle?
(1) 3422 sq.mtrs.
(2) 3242 sq.mtrs.
(3) 3244 sq.mtrs.
(4) 3424 sq.mtrs.
(5) None of these

• 2*pi*r1=88
  r1=14.
  
  2*pi*r2=220
  r2=35
  
  diff bw areas is = pir2^2-pir1^2
  
  pi(r2^2-r1^2) [ a^2 - b^2 = (a+b)(a-b) ]
  pi(49*21)=3234 sq.m
