Answer:
31.42 ft
Step-by-step explanation:The formulae used for the area of a circle is
A = pi * (radius)^2
where r is the radius of the circle
We know that the area is 25 pi so substitune that into the formula
25pi = pi(r^2)
r^2 = 25
radius = sqrt 25
= 5 ft
si we ignore the negative value of the square root since he radius cannot be negative.
Next we look at the formula for the circumference of a circle
C = pi(d)
= pi *(2r)
= 2(5)(pi)
= 10pi
= 31.42 feet
