Answer:

18.2 cm

Step-by-step explanation:

Circumference of a given circle is 57.2cm

∴C=57.2cm

Let the radius of the given circle be r cm

Then,

C=(2πr)units

r=( C/2π)

r= 57.2/ 2×22/7

r = 57.2/2 × 7/22

r = (28.6 ×0.3182)

r = 9.1 cm

So the diameter is the double of the radius ....

diameter= 2×9.1

Diameter = 18.2 cm
