The previous owner built a small round pond in the garden, it wasn't finished and I'm hoping to do so, but I do have a problem. The pond is perfectly round with a circumference of 411cm, and I have a sufficient number of 5cm square slate tiles to go on top of the small retaining wall. Is there a formula or method to work out the angle the sides of the tiles need to be cut to give me a circle that will fit the pond?
Using Zac's calculation (which is correct) you'll be taking 2.2 deg off 2 sides of each tile. In all honesty, it's going to look just as good to lay them as is and fill the tapered gap with grout.
Thank you all for replying so quickly. The tiles are thin and I have a good electric tile cutter so I'll give it a go. many thanks Zacs that is what I was looking for.
