Answer:
since, Here conversion of rectangle into circle
therefore,
perimeter of rectangle = perimeter of circle
2(l + b) = 2 pie r
2 (35 + 31 ) = 2 *22/7* r
2* 66 = 2*22/7*r
r = 21
therefore radius = 21 cm Answer..

Step-by-step explanation:
A rectangle is made from wire whose length is 35cm aND breadth is 31
and we find the radius of circle is ?
so the perimeter of rectangle =the perimeter of circle
2(l+b)=2πr
2(35+31)=2x22/7xr
2(66)=2x22/7xr
132=44/7xr
132x7/44=r
942/44=r
21=r
this is because rectangle and circle are made from equal wire
