When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
Simple, it it is a true barrel simple find the measurement from inside to inside of your barrel and divide by 2. IF it is not a perfect half circl barrel or true barrel, simple find your chord (measurement inside to inside) and find your rise. Once you have these measurements you can use your diameter formula to figure the radius
Radius = Diameter/2 Diameter = 2* Radius
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

Multiply the radius by 2 x pi.Multiply the radius by 2 x pi.Multiply the radius by 2 x pi.Multiply the radius by 2 x pi.
The inside lane is called lane one.
The formula for the surface area of an elbow (or 90° angle) is (pi^2 * (radius2^2 - radius1^2) ) / 4. Where pi = 3.14159, radius 2 = the radius from the center to the outside, and radius 1 = the radius from the center to the inside.
inside lane
1/2 inch
Its according to which side of the highway your entering from...If entering from the left side of road then the left side is the inside lane.....if entering from right side then the right lane is the inside lane.....
Outside
High Occupancy Vehicle (HOV) / carpooling lane - allowing only vehicles with 2 or more people inside .
Usually the size of a track is determined by the inside measurement, and the track becomes longer in the middle lane, and even longer yet in the outside lane. this is why you see them at most tracks qualify on the inside lane, its shorter.
The stagger is done so that everyone runs the same distance. The runners that start on the inside lanes start farther back, because the outside lanes are longer. This way everyone runs the same distance no matter which lane they are assigned.
In Australia, where there are two parallel lanes for vehicles traveling in the same direction, the right hand lane is referred to as the "outside lane" and the left hand lane, closest to the curb, is the "inside lane".
The length of a 400-meter track is actually measured along a "measuring line" that is located in lane 1. The measuring line is exactly 400 meters. The actual location of the measuring is based upon whether there is a raised curb on the inside of track, or not. Go to NCAA.ORG for the specific measurement to the lane. It's approxiamtely 30 from the outside edge of the interior lane 1 line (which is 2-inches wide) for raised curbs, and approximately 20 cm from the outside edge of the interior lane 1 line for no curbs at all.
Outside lane for half-way around or less, inside lane for half-way around or more. Those are the guidelines I'd always followed. Since the exit you want is 4 out of five, that's more than half-way around, you should be on the inside lane. BTW, if you're going exactly half-way around (doesn't apply with five exits, as nothing is exactly 1/2), you can take either lane.
