Answer:
Step-by-step explanation:
The circumference of a circle's formula is pi*d (d being diameter).
If it only shows you the radius, then the formula would be 2*pi*r (r being radius), this is the same as pi*d.
2*r = d
Question 2
The circle has a diameter of 100m. Find circumference
pi*d
pi*100
314.16m in total
