Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.

Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:

r= 10 ft

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
