Working on a estimate for some tree rings. Is there a formula somewhere? Cannot find one. For circle rings. one i have to do has a diameter of 6' and needs to be about 4 blocks high. How can I figure out how many blocks I need? Blocks are 3.94x7.9x11.8 Thanks for any help you can give.

maybe just figure out the circumference of the circle in inches, then figure out how many blocks you need to make a line that long.

Then muliply x 4

That should get you within a couple blocks I would think.

Pi= 3.14 times R2

Pi= 3.14 times R2 or 3.14 times the diameter.
