Amerry-go-round has a radius of 10 ft. to the nearest tenth of a foot, what distance does the merry-go-round cover when it rotates through an angle of 72°?

for my first try, i got 62.9 as my answer, and it was marked wrong. i did this a second time, and got 12.6. i would like to check with anyone else to see if i got the answer right.

the answers for this question were:

62.9, 12.6, 25.1, or 125.7
