Calculate the radius (r) of a circle with a circumference of 56.52 feet.
r = C ÷ π/2
Use 3.14 for π

1 answer

To calculate the radius (r) of a circle with a given circumference (C), we can use the formula for the circumference of a circle:

\[ C = 2\pi r \]

Given that the circumference \( C = 56.52 \) feet and using \( \pi \approx 3.14\):

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

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

  1. Substitute \( C \) and \( \pi \) into the equation:

\[ r = \frac{56.52}{2 \times 3.14} \]

  1. Calculate \( 2 \times 3.14 \):

\[ 2 \times 3.14 = 6.28 \]

  1. Now, substitute this back into the equation for \( r \):

\[ r = \frac{56.52}{6.28} \]

  1. Perform the division:

\[ r \approx 9.00 \text{ ft} \]

Thus, the radius \( r \) of the circle is approximately 9.00 feet.
