Question

find the diameter of the circle whose circumference is 1.32 cm​

Answer 1

Step-by-step explanation:

2x(22/7)x r

1.32= 44r/7

1.32x7= 44r

9.24= 44r

9.24/44=r

0.21=r

Diameter = 2r

= 0.21 X2

0.42

Answer 2

Step-by-step explanation:

circumference=2πr

so therefore,

1.32cm= 2πr

1.32cm=2×22/7×r

1.32cm×7/2×22=r

101.64=r

therefore diameter =2×radius

=2×101.64

=202.82cm
