what is the approximate value of 80 meters

Question

what is the approximate value of a 80 inch circle.

Answer 1

There seem to be two different questions here.

 

Each one can be answered using the basic fact that l meter is about 39.37 inches.

 

"an 80 inch circle" is not a clear concept; circles can be classified by either the radius, or the diameter, or the area, or even the circumference. You gave a number but did not identify what it measures.
