Question

a wire of length 132 cm is bent as a circle . what is the radius of the circle ​

Answer 1

Answer:

21 cm is the radius

solution:-

Length of the wire will become the circumference of the circle.

so ,

circumference of the circle is 132 cm.

circumference = 2πr

132 = 2×22/7×x

132 = 44x/7

132×7 = 44

924 = 44x

x= 924/44

x= 21

hence the radius is 21 cm.
