Circumference of a circle = π x D
C = 3.14159 x 38
C = 119.38 inches
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
if the diameter is in feet then multiply the diameter by pi 38 x 3.14159 = 119.38042 square feet if the diameter is in inches then dividethe inches by 12 then multiply the diameter by pi 38 ÷ 12 = 3.16666 x by 3.14159 = 9.94835 square feet
Circumference = pi*38 = 119.3805208 or about 119.381 inches

It would be the tread face width by the rim diameter. For instance if you have a 13.6 X 38 tire, which was common on older tractors, it would be 13.6 inches across the tire tread area and 38 inches diameter inside the bead , or 38 inches across the rim to where the tire bead seats which is slightly less than the total distance across the rim.
Diameter = Circumference/pi = 38/pi = 12.1 inches

38 millimeters is 1.5 inches or 0.12ft
38 inches
pi*diameter = 38 Divide both sides by pi to find the diameter: diameter = 12.09577567 or 12 inches to the nearest inch.
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
12 inch diameter(also 6 inch radius).
38 millimeters = about 1.5 inches. (1.49606299 inches)
