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
