Answer: See explanation
Explanation:
Your question isn't complete but I'm assuming that you want to calculate the radius.
Circumference of a circle = 2πr
where Circumference = 18.9 meters
Radius = Unknown
π = 3.14
We then put the values into the formula which will be:
C = 2πr
18.9 = 2 × 3.14 × r
18.9 = 6.28r
r = 18.9 / 6.28
r = 3
The radius = 3 meters
Assuming you probably want to get the diameter, we multiply the radius by 2. This will be:
= 2 × 3
= 6 meters
