A water sprinkler sprays in a circular a distance of 10 ft. What is the circumference of the spray?
I got 31.4 ft.
Is that right??

Yes, you are correct.
Key word is circular, so we are talking about a circle. pi = circumference of a circle / diameter > pi = C / d
Solve for C
C = pi*d = (3.14) *(10 ft) = 31.4 ft, assuming the approximation of 3.14 for pi.
