Answer:
The answer to your question is Circumference = 81.64 ft
Step-by-step explanation:
Data
Area of a circle = 530.66 ft²
Circumference = ?
π = 3.14
Process
1.- Calculate the radius of the circle
Area = πr²
-Solve for r²
r² = Area / π
-Substitution
r² = 530.66 / 3.14
-Simplification
r² = 169
-result
r = 13 ft
2.- Calculate the Circumference
Circumference = 2πr
Circumference = 2(3.14)(13)
-Result
Circumference = 81.64 ft
D. enlargement
enlargement means to increase something
1080 degrees
180(n-2) = sum of all interior angles
180(6) = 1080
