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

The ball used in table tennis has a diameter of d = 40 mm. Some time ago it was 38 mm. 40mm=4cm, 4cm/(2.54cm/in)=1.575 (rounded) 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
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
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.
To convert millimeters to inches, you can use the conversion factor where 1 inch is equal to 25.4 millimeters. Therefore, to convert 38 mm to inches, you divide 38 by 25.4, which equals approximately 1.5 inches. So, a diameter of 38 mm is about 1.5 inches.
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)
