well it depends on the straw but here's how you can find it ... put a ruler down right on the circle (side) make sure it is symmetrical then measure that and thats the damiter the circumrence is three and one 7th on the diameter
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
diameter = circumference/pi
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
diameter = circumference/pi
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
Circumference = pi*diameter So diameter = circumference/pi = 9.87 mi
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
