Find 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 find the radius (r) of a circle with a given circumference (C), you can use the formula for circumference:

\[ C = 2\pi r \]

Given:

  • \( C = 282.6 \) ft
  • \( \pi \approx 3.14 \)

We can rearrange the formula to solve for the radius (r):

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

Substituting the values:

  1. Calculate \( 2\pi \):

    \[ 2\pi \approx 2 \times 3.14 = 6.28 \]

  2. Now substitute this into the formula for r:

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

  3. Perform the division:

    \[ r \approx 44.93 , \text{ft} \]

Therefore, the radius (r) of the circle is approximately 44.93 feet.
