Respuesta :
S = pi*R^2 = 324 sq feet
(pi ≈ 3.14)
=> R ≈ 10.16 feet
C = 2*pi*R ≈ 63.8 feet
(pi ≈ 3.14)
=> R ≈ 10.16 feet
C = 2*pi*R ≈ 63.8 feet
Answer:
The circumference of the circle is approximately 56.55 feet.
Step-by-step explanation:
To find the circumference of a circle using only the area, you can use the formula:
Area = πr^2
Given the area is 324 feet, you can solve for the radius (r):
324 = πr^2
r^2 = 324 / π
r ≈ 9
Now that you have the radius (r = 9), you can use the formula for the circumference of a circle:
Circumference = 2πr
Circumference = 2 * π * 9
Circumference ≈ 56.55 feet
Therefore, the circumference of the circle is approximately 56.55 feet.
