Method for make traditional woodworking small round table

Solution: As shown in the figure, it is a semicircle with the largest radius.

If FD is connected, DF will pass through the tangent point q,

More than d stands for DM⊥AF stands for m,

Let the radius of the circle be r,

Then FM=2-2r, DF=2r, DM=AB= 1.5,

From Pythagorean Theorem: DM2+MF2=DF2

∴ 1.52+(2-2r)2=(2r)2，

Solution: r = 0.78 125.

So the answer is: 0.78 125.
