kaise?
Try something different..for objectives if length increase by a% and breadth increases by b% then area increases by =(a+b+ab/100)% for circle its all two dimensions will increases by 1% so,net areal increase =(1+1+1×1/100)=(2+.01)%
ohhh thnku
For subjective let radius be 100unit area,A1=π100×100 and new radius=101 unit so area,A2=π101×101 =
10201π so, area increase by π(10201-10000)=π201.and % INCREASE =π201/π10000×100=201/100%=2.01%
10201π so, area increase by π(10201-10000)=π201.and % INCREASE =π201/π10000×100=201/100%=2.01%
