Answer:
10(pi)ft
Explanation:
the formula for the area of a circle is Pi R^2
if we set this equal to the given area, 25(pi)ftsq=(pi) r^2
and we can cancel between the sides to 25ftsq = r^2, square rooting both, we can find r to equal 5ft.
With this in mind, acknowledging the circumference formula to be 2 (pi) r, we can simply plug it in to get, 2 times 5ft time (pi), or 2*5ft*(pi), or 10(pi)ft
