Calculate the radius (r) of a circle with a circumference of 282.6 feet.
r = C ÷ π/2
Use 3.14 for π

1 answer

To calculate the radius of a circle using the circumference, we can use the formula for circumference:

\[ C = 2\pi r \]

Given that the circumference \(C = 282.6\) feet, we can solve for the radius \(r\):

  1. Rearrange the formula to solve for \(r\):

\[ r = \frac{C}{2\pi} \]

  1. Now substitute \(C\) and \(π\) (using \(3.14\) for \(\pi\)) into the equation:

\[ r = \frac{282.6}{2 \times 3.14} \]

  1. Calculate the denominator:

\[ 2 \times 3.14 = 6.28 \]

  1. Now divide \(282.6\) by \(6.28\):

\[ r = \frac{282.6}{6.28} \approx 44.95 \]

Therefore, the radius \(r\) is approximately \(44.95\) feet.
