Length of wire = 4a
= 4 × 66 cm
= 264 cm
Now,
Circumference of circle = Length of wire
2 π r = 264 cm
r = (264 cm) / (2 π)
= 42 cm ………[Take π = 22/7]
Radius of circle is 42 cm
= 4 × 66 cm
= 264 cm
Now,
Circumference of circle = Length of wire
2 π r = 264 cm
r = (264 cm) / (2 π)
= 42 cm ………[Take π = 22/7]
Radius of circle is 42 cm
