Hi Guys,
Not sure I have worded the title correctly
I am looking to calculate the distance around an arc, given A-B = 70
and the depth is 70cm
Thanks

To accurately determine the length of an arc you really need the radius of the circle it is taken from.
However, it can be estimated like this
=SQRT(A1^2+16/3*A2^2)
where A1 and A2 are the straight line AB and the ARC AB
Rule 1: Never merge cells
Rule 2: See rule 1

Hi, Presumably the shape is an ellipse or parabola, as with those dimensions its hard to see how it could be an arc of a circle !!

Hi Guys
Not really an arc or Para whatever.
These are made out of material and have to have a trim round the edge, looking for a way to calculate before the application of the trim
Thanks anyway
Hi Guys,
Another one for you
Same excel sheet, sort of a triangle need to know the length of the edge
cheers
=sqrt( sumsq( c21-c37, b28-e23)) ~ 170.4
Entia non sunt multiplicanda sine necessitate
That was from the second sheet you posted -- it's the length of the chamfer.
Hi, With regards to the first Question :- See the attached
