Help!! what is the circumference of a circle which is 66 inches in diameter

[johnk]

Multiply by pi (no symbol on this keyboard) 3.142

207.37in or approx 17.3ft.

[beveridge111]

Thank you both I am no mathematician!!!

[Sqad]

I get 34 ft.....LOL

c=2piR Where pi is 3.14 and the R =66ins.

c=6.28 x 66= 414 inches = 34ft approx

Where have I gone wrong?

[redcrx]

sqad, the diameter is 66 inches.
Thefore the radius is only 33 inches for your calculation

[ChuckFickens]

r = 33 inches

The diameter is 66inchs, not the radius

[Fibonacci]

you used value of radius in your formula as 66 inches
If diameter is 66 inches then radius = 33 inches.

[factor-fiction]

If diameter is 66 then radius is only 33

[ChuckFickens]

So that seems to be pretty unanimous then :)

[Sqad]

Of course....thanks all.....I will stick to Relationship and Dating for my posts in future.

About 6 inches?

[ChuckFickens]

I have seen that problem before, but the other way round (i.e. if you added 1foot to the rope what would the slack be all around the earth?)

[McMouse]

Your rope thing has a flaw doc. If the rope passed through our village the pikeys would nick most of it.

Measuring slack is a different issue altogether, first we need a definition of slack.
