a full revolution of a circle is 18.84 cm
Full revolution is the circumference of the circle
we are given with circumference of the circle 18.84 cm
We need to find the diameter of the circle
Formula for the circumference of the circle is =
Where d is the diameter of circle
we assume the value of pi as 3.14
the circumference of the circle is =
18.84 = 3.14 * d
To isolate 'd' we divide both sides by 3.14
d = 6
the diameter of the circle is 6 cm
