Question

a wire is in the shape of a square of side 10.5 each. the same wire is bent in form of a circle. find the radius of circle​

Answer 1

Step-by-step explanation:

at first find the perimeter of square

perimeter=4×side

4×10.5=42

therefore,42=2πr

let r =x

42=2×22/7×x

42×7=2×22×x

294=44×x

x=294/44= 6.6

so, radius of circle=6.6
