Answer: Diameter of circle = 18m
Step-by-step explanation:
Given that distance around a circle is = 56.55 meter
The distance around a circle on the other hand is called the circumference .
That means Circumference = 56.55 m
We know the formula of circle's circumference= 2πr
where r is the radius and 2r is diameter of the circle
So,
2πr = 56.55
divide by π both the side
2r =
Value of π =

2r = 17.993 ≈ 18 m
Diameter of circle = 18m
