71.8 metres does not define a shape and so does not have any particular perimeter.
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
Multiply the area squared minus the radius
The perimeter of a rectangle is length + width x 2 = perimeter. * * * * * That is misleading since that would be evaluated as L + W2 or L + 2W. The perimeter of any polygon is the sum of the lengths of its sides. A rectangle has two sides of the same length (L) and the other two of the same width (W). So the perimeter is 2*L + 2*W or 2*(L + W).
That depends on exactly what you want to 'do' to it or with it. Do you want to calculate it ? Spell it ? Define it ? Walk around it ? Send it in Morse Code ? The perimeter of an area or object is the total distance around its boundary. Measure each side with a ruler, yardstick, tape measure, etc. Then add all of these numbers together, and you have the perimeter.
Perimeter is the sum of length of all sides of a geometrical figure.

That depends how you define the perimeter for a cube. The term perimeter is usually used for plane figures, not for 3D solids.

Ratio of the perimeter of a circle (circumference) to its diameter
The circumference of a circle is the perimeter of the circle for a given diamater.

By integration. Divide the curve into small pieces, then add up the length of all the pieces.
You will have walked about 10.92 miles in perimeter. * * * * * That is a total rubbish answer. An area does not and cannot define a perimeter. An area of 3 acres can comprise an extremely thin strip stretching millions of miles. So the perimeter would also run to millions of miles. And if the strip was thinner, it could be billions of miles or trillions, etc.
Define the perimeter of the TLOF with a continuous 12in line. The marking of the perimeter of a paved FATO would consist of a 12in wide dashed line with 5ft mark and 5ft gap. Define the perimeter of unpaved FATO with 12in thick dashed line consisting of flush-in ground markers, 5ft mark and 5ft gap. The safety area does not need to be marked. The size and thickness of the TDPC markings is dependent upon the size of the helicopter the Helipad is being designed for.
