You can use proportions to solve this problem:
x%2FC+=+40%2F360 Where: x = the required distance along the circumference and C = the entire circumference. C+=+%28pi%29D and D = 40 ft.
x+=40%2840%28pi%29%29%2F360
x+=+1600%28pi%29%2F360
x+=+4.44%28pi%29 Using %28pi%29+=+3.14 as an approximation.
x+=+13.96 feet.
