To find the radius \( r \) of a circle with a circumference of \( C = 69.08 \) feet using the formula for circumference \( C = 2\pi r \), follow these steps:
-
Rearrange the formula to solve for \( r \): \[ r = \frac{C}{2\pi} \]
-
Substitute the value of \( C \) and \( \pi \) (using 3.14): \[ r = \frac{69.08}{2 \times 3.14} \]
-
Calculate \( 2 \times 3.14 \): \[ 2 \times 3.14 = 6.28 \]
-
Now divide \( 69.08 \) by \( 6.28 \): \[ r = \frac{69.08}{6.28} \approx 11 \]
So, the radius \( r \) is approximately \( 11 \) feet.
Given \( C = 69.08 \) feet, your answer for the radius \( r \) is: \[ r \approx 11 \text{ ft} \]
