area of square = area of circle
121sq.cm=2*22/7*r
r =121*7/44
=847/44
=19.25cm
area of circle =2*22/7*370.56
=2329.23sq.cm
121sq.cm=2*22/7*r
r =121*7/44
=847/44
=19.25cm
area of circle =2*22/7*370.56
=2329.23sq.cm

A steel wire when bent in the form of square encloses an area of 121 cmsquare.
area of square =side ×side
121 = side ²[because side ×side is side²]
side²=121
side =√121=11cm
he same wire is bent in circle
so the perimeter of circle is 44
perimeter of cirlce = 2×22/7×radius
11 =44/7××radius
radius=44/7×44=7 cm
arae = 22/7×radius²
=22/7×7²
=154cm² [not 132]
the area is 154cm²

ok
brainliest?
the first guys' answer is completely wrong.at least for me the final step is wrong.so please mark as a brainliest
aiyoooo
are you not abe to understand hat i am saying?
no
how radius=7 cm can u explain
see 11 cm is the perimeter
