The formula for circumference is 2nr.

First we need to find 'r' which stands for radius (the straight distance from the centre of the circle to the edge). Since the radius is half of the diameter, the radius is 70/2=35 yds.

Now we can put 35 yds into the formula: 2*n*35 = 219.91 yds (rounded to 2 decimal places).
