The area of a circus ring is about 1,385 square feet. What is the circumference of the ring?

A = pi * r^2

1385 = 3.14 * r^2

1385/3.14 = r^2

44.108 = r

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

C = pi * d

C = 3.14 * 88.2

C = ?

use area of circle formula.

a=pi r^2
c=pi d

Thus, we need to plug in numbers. 1385/pi = r^2. We take the square root of that to get the radius.Then, we can double that radius and multiply by pi to get the circumference.

the formula would be 2pi sqrt1385/sqrt pi

To find the circumference of the circus ring, we need to use the formula for the circumference of a circle.

The formula for the circumference of a circle is:

C = 2πr

Where C represents the circumference, and r represents the radius of the circle.

To find the radius, we need to find the square root of the area (A) divided by π (pi).

Let's calculate the radius of the circus ring first:

r = √(A/π)
r = √(1385/π)
r ≈ √(441)
r ≈ 21

Therefore, the radius of the circus ring is approximately 21 feet.

Now, we can use the radius to find the circumference using the formula:

C = 2πr
C = 2π(21)
C ≈ 42π

So, the circumference of the circus ring is approximately 42π feet.

To find the circumference of a circus ring, we can use the formula:

C = 2πr

where C is the circumference, π (pi) has a constant value of approximately 3.14159, and r is the radius of the circle.

Now, we are given the area of the circus ring, not the radius. So, to find the radius, we need to find the square root of the area.

Let's calculate the radius:

√(Area) = √(1,385)
Radius ≈ 37.20 feet (rounded to two decimal places)

Now that we know the radius, we can find the circumference:

C = 2πr
C = 2 * 3.14159 * 37.20
C ≈ 233.60 feet (rounded to two decimal places)

Therefore, the circumference of the circus ring is approximately 233.60 feet.
