The circumference of a circle is 35 pi. what is the diameter?
if your circumstance is 35pi then the formula would be c=35pi and to find that it would have been c=2 pi r. to find the diameter it would be d=c/pi. so it would be d=35pi/pi. the pi's would cancel out and you have 35 as the diameter and 17.5 as the radius
c=2 pi r
c= 2 pi 17.5
i hoped this , i am not sure but this is what i think
30 / 0.350 = 85.7
you can fill up 85 bottles.
