circumference=88cm 2πr= 88
radius=14 cm
area=πr2=616 cm2
area of square=s*s =30*30=900 cm2
area of paper left=900-616= 284 cm2, ans

circumference=88
so radius be r nd now A.T.Q
88= 2πr
88/2= 22/7×r
44×7/22= r
so r = 14
now area of circle = πrsq.
= 22/7 ×14×14
area = 616 cm sq.
area of sheet = side ×side
= 30×30
= 900
remaining area = 900-616 = 284 cmsq.
this is ur answer
